Prairie Grain Transportation
Prairie grain transportation moved 49 million tonnes of Western grain in the 2024-25 crop year — a 12 per cent increase over the prior year and one of the largest single-year volumes ever recorded. The Port of Vancouver posted record bulk grain throughput of 30.3 million tonnes in 2025, including a 20 per cent jump in wheat exports. CPKC opened the 2025-26 crop year with a new January carload record of 24,688 carloads and 2.395 million tonnes in a single month. By most headline measures, the Prairie grain transportation system is performing better than it has in years.
But headline volume records do not tell producers what they need to know about whether their grain will move when they need it to move. The system’s structural vulnerabilities — dependence on two railway companies, a single marine choke point at the Second Narrows rail bridge in Vancouver, concentration of export capacity at West Coast ports, and the regulatory framework that governs how much railways can charge — remain unchanged regardless of record-setting months. In 2026, a new variable has been added: the Iran war’s effect on global marine freight rates and shipping insurance costs has created ripple effects in bulk shipping economics that are relevant to how Canadian grain trades at export terminals.
This page is the Western Farm Report’s reference hub for Prairie grain transportation. It covers the rail system — CN and CPKC performance, car ordering, the Maximum Revenue Entitlement framework — port infrastructure, export corridor risks, producer car program mechanics, interswitching, and the regulatory tools producers can use when service fails. It is updated on a rolling basis through the growing season.
The Scale of the System: What 49 Million Tonnes Requires
The Canadian Transportation Agency’s December 2025 determination for the 2024-25 crop year confirmed that 49,002,694 tonnes of Western grain moved through the regulated rail system — a number that contextualizes what the CN and CPKC networks are required to deliver year after year. To put that in operational terms: 49 million tonnes over a 365-day crop year requires moving roughly 134,000 tonnes per day, every day, across a network that must simultaneously handle winter cold, spring flooding, wildfire season disruptions, port labour actions, and demand surges following harvest. The record is meaningful, but the more relevant metric for producers is consistency of performance throughout the year rather than peak-month records.
The CTA’s 2024-25 ruling also produced a notable outcome on the Maximum Revenue Entitlement: CN’s grain revenue of $1.454 billion was $5.9 million below its entitlement of $1.460 billion — meaning CN had room to charge more but did not. CPKC’s grain revenue of $1.066 billion was $2.66 million above its entitlement of $1.064 billion — meaning CPKC exceeded its revenue cap. Under the Canada Transportation Act, CPKC is required to pay the overage plus a five per cent penalty to the Western Grains Research Foundation. The penalty is not financially punishing at $2.66 million against $1 billion in grain revenue, but the MRE determination signals that CPKC’s rate-setting during a high-volume year pushed through the ceiling — a data point that shippers and their advocates track carefully.
Looking ahead, the CTA set the Volume-Related Composite Price Index (VRCPI) for the 2026-27 crop year in late April 2026, with CN at a 0.659 per cent increase over 2025-26 and CPKC at 0.646 per cent. The VRCPI is the inflation factor used in setting each railway’s MRE — modest increases that reflect the railways’ input cost forecasts for labour, fuel, and capital. These will be used in the December 2027 determination for the 2026-27 crop year.
MRE explained — what the revenue cap means for Prairie grain shippers
CN and CPKC: Grain Plans, Car Fulfilment, and What the Numbers Mean
Both CN and CPKC publish annual grain transportation plans at the start of each crop year, setting volume targets and outlining their operational commitments. For 2025-26, CN projected movement of 27 to 29.5 million tonnes of grain and processed grain products. CPKC did not publicly specify a single target but entered the year having moved more than 15.1 million tonnes through the first 26 weeks — the largest first-half total since the record 2020-21 crop year.
CN made a notable operational change in its 2025-26 grain plan: instead of distributing empty hopper cars returning from West Coast ports at Prairie rail hubs, CN shifted to distributing cars as they depart Vancouver. The intent is to improve shipper visibility on car availability and reduce the lag between a car leaving a port terminal and being visible to the originating elevator for planning purposes. CN also committed to weekly stakeholder updates on car orders, supply chain conditions, and system fluidity through its Western Canadian Grain Report — a transparency measure that is operationally useful but only as valuable as the timeliness and accuracy of the data it reports.
Car order fulfilment rate is the metric that matters most to elevator operators and producers shipping on producer cars. Industry benchmarks from the Ag Transport Coalition — which monitors weekly fulfilment across both railways on behalf of grain shipper groups — indicate that performance at or above 85 per cent of ordered cars delivered is considered acceptable, while 90 per cent or above is good. Performance consistently below 80 per cent signals systemic capacity stress and triggers the kind of elevator inventory backup that widens basis at country elevators. When car fulfilment falls into the 50 to 60 per cent range — as happened during the B.C. flooding and COVID-related disruptions in the 2021-22 crop year — the consequences cascade rapidly: grain backs up at elevators, basis widens to rationing levels, and producers who were holding grain expecting normal movement find themselves competing for limited shipping slots against elevator companies with contracted volumes.
The 2025-26 crop year has not reproduced those crisis conditions. Both railways entered the year with improved equipment fleets — CN distributing a new generation of covered hoppers, CPKC having largely completed its transition to high-efficiency 8,500-foot unit train equipment capable of carrying approximately 44 per cent more grain per train length than previous-generation consists. These equipment improvements are structural gains for the system’s overall capacity. The question is whether that capacity is consistently utilized at the throughput rates the railways project, or whether the headline efficiency gains are absorbed by the same recurring disruptions — winter cold, port slowdowns, crew shortages — that have constrained grain movement in past crop years.
The Maximum Revenue Entitlement: How It Works and Why It Matters
The Maximum Revenue Entitlement is the central regulatory instrument governing what CN and CPKC can earn from shipping Western Canadian grain. It was introduced in 2000 as a replacement for the previous rate-cap system and is administered by the Canadian Transportation Agency under the Canada Transportation Act.
The MRE does not set a fixed rate per tonne. Instead, it sets a ceiling on each railway’s total annual revenue from regulated Western grain movements. The ceiling is calculated using a formula that accounts for three variables: the volume of grain moved, the average length of haul, and the Volume-Related Composite Price Index — the inflation factor the CTA sets each April for the upcoming crop year. The practical consequence is that if a railway moves more grain or longer hauls in a given year, its MRE rises proportionally. This design means railways are not discouraged from moving additional volume, because the revenue ceiling expands with volume. Railways that exceed their MRE must pay the overage plus a five per cent penalty to the Western Grains Research Foundation, which directs the funds to crop research benefiting Prairie producers.
What the MRE does not do is guarantee producers specific rates or service levels. A producer shipping grain to Vancouver does not have a regulated rate — the elevator company contracts with the railway, and those commercial rates are negotiated within the MRE ceiling. The MRE limits total system revenue at the portfolio level, not the individual shipment level. Rates for specific corridors and commodities can vary considerably above and below any average, as long as the total portfolio stays within the ceiling.
The MRE also does not address service quality directly. A railway can technically comply with its MRE while delivering poor car fulfilment rates, slow cycle times, and inconsistent service — as long as the revenue it collects stays within its ceiling. Service quality enforcement relies on a separate set of provisions in the Canada Transportation Act, including the level of service obligations and the shipper remedy framework that allows shippers to file complaints with the CTA when service falls below statutory requirements.
The CTA’s 2025-26 departmental plan flagged an ongoing legislatively-required review of the Railway Interswitching Regulations as an active priority for 2025-26. Interswitching — the right of shippers in certain zones near railway interchange points to access a competing railway’s services — is a competition tool that provides some leverage against the de facto duopoly that CN and CPKC represent in most Prairie shipping corridors. The interswitching review matters because expanded interswitching zones would give more Prairie shippers access to rate competition, while restricted zones would entrench existing commercial relationships. The outcome of this review will have direct consequences for grain shipping economics in affected corridors.
Port Infrastructure: Vancouver’s Record Throughput and Its Structural Limits
The Port of Vancouver processed a record 170.4 million tonnes of total cargo in 2025 — an eight per cent increase over the 2024 record — with bulk grain exports reaching 30.3 million tonnes, up four per cent from 2024. Wheat exports through the port hit a record 15.9 million tonnes, up 20 per cent, reflecting the strong 2025 Prairie wheat crop and aggressive export program. Potash exports set a record at 10.5 million tonnes and crude oil through the Trans Mountain expansion more than doubled to 24.4 million tonnes.
These are significant numbers, and they reflect genuine infrastructure investments that have expanded the port’s throughput capacity over the past decade: Viterra and Richardson’s Cascadia terminal railyard expansion adding approximately 1,500 metres of track and enabling 2,600-metre train assembly, CPKC’s shift to 8,500-foot unit trains, CN’s car distribution changes, and the Trans Mountain expansion unlocking tanker loading capacity at Westridge. The port authority has described itself as uniquely positioned to support Prime Minister Carney’s stated goal of doubling Canadian exports to non-U.S. markets over the next decade, and the infrastructure investments of the past five years provide a genuine foundation for that claim.
What the record throughput numbers do not resolve is the system’s exposure to a single structural vulnerability: the Second Narrows rail bridge. The CN-owned lift bridge is the only rail access to the North Shore grain, potash, and coal terminals in Vancouver. It opens multiple times daily to allow vessel traffic through Burrard Inlet. In late February 2026, the bridge locked in its down position for several days — a mechanical failure that prevented approximately 13 ships from transiting the narrows and disrupted North Shore terminal operations. The disruption was resolved without major systemwide impact, but it highlighted a vulnerability that has existed for years and that no amount of Prairie rail investment or elevator expansion can remedy: a single 58-year-old lift bridge is the physical chokepoint for a significant share of Canadian grain export capacity.
The port authority has characterized infrastructure controls and procedures around the Second Narrows as adequate, and engineering assessments of the bridge’s seismic resilience have been completed. The practical concern is that widening the throughput funnel upstream — more cars, more trains, more elevator capacity — while leaving the chokepoint unchanged means that any future bridge disruption cascades into a larger backup than it would have a decade ago, simply because more tonnage is dependent on that single point of passage. An extended failure of the Second Narrows bridge during peak export season would be a material event for Prairie producers holding grain and watching basis widen.
Prince Rupert’s grain terminal provides the system’s most significant alternative routing. As of early 2026, Prince Rupert had moved approximately 2.92 million tonnes through week 30 of the crop year, slightly ahead of the prior year’s 2.83 million tonnes. The Prince Rupert terminal provides a genuine routing alternative with strong performance characteristics and less port congestion than Vancouver — and its throughput has grown consistently over the past decade. For producers and elevator companies evaluating corridor risk, Prince Rupert is an increasingly relevant option in a system where Vancouver concentration is a known vulnerability.
Thunder Bay handles Eastern movement of Western grain — primarily through the Great Lakes system for spring, summer, and fall movement before freeze-up. Thunder Bay’s role is most relevant for durum and hard red spring wheat moving to eastern Canadian millers and for some export volumes through St. Lawrence ports. The port is closed to navigation through winter months, which concentrates movement pressure on West Coast corridors in the November-to-March period. Rail corridor balance between Vancouver, Prince Rupert, and Thunder Bay is a genuine operational lever for the railways — and a point of sustained negotiation between CN and grain shippers who use eastern routings.

Marine Freight in 2026: What the Iran War Has Changed for Grain Shipping
The closure of the Strait of Hormuz following the late-February 2026 Iran war has not directly affected Canadian grain export routes, which move from Vancouver and Prince Rupert across the Pacific to Asian markets, or through Panama to European and North African buyers. None of those primary Canadian export routes pass through the Strait. However, the Strait’s closure has created meaningful indirect effects on global bulk shipping economics that ripple into the rates and terms at which Canadian grain moves.
The Strait of Hormuz carries approximately 14 million barrels per day of oil and significant volumes of LNG under normal conditions, according to the International Energy Agency. The disruption to this volume has forced oil tankers and LNG carriers to reroute — some via the Cape of Good Hope around Africa, adding significantly to voyage times and fuel costs. This rerouting has tightened the global vessel supply available to the bulk grain shipping market. When tankers and bulk carriers are tied up in longer voyages, vessel availability for grain shipments contracts, which tightens bulk freight rates globally.
War risk insurance premiums for vessels operating in or near the Strait have spiked to levels that effectively price out standard commercial operation for any shipping company without specialized war risk coverage. This has removed a significant number of vessels from the active global trading fleet — not because they are damaged, but because they cannot be insured for Middle East routes at commercially viable premiums. The tightening of available vessel supply has pushed Panamax and Supramax bulk carrier rates higher in markets that directly compete with Canadian grain export routes.
For Prairie producers, the practical consequence is that freight rate costs embedded in the basis at Prairie elevators reflect, among other things, the ocean freight cost from Canadian ports to export destinations. When ocean freight rates rise, the delivered cost of Canadian grain to foreign buyers increases, which puts downward pressure on the price those buyers will bid — all else equal. The ocean freight effect competes with the supply-shortage effect from Middle East disruption: buyers who cannot source from Hormuz-constrained exporters need Canadian supply more urgently, which supports price; but the cost of getting that supply to them is higher, which pushes the negotiated landed price lower. The net effect on Canadian cash prices depends on which force dominates in any given week.
Producer Cars: Direct Rail Access and What It Requires
The producer railway car program is one of the few tools in the grain transportation system that gives Prairie producers direct access to rail capacity without going through an elevator company. Under the program, administered by the Canadian Grain Commission, individual producers or producer groups can apply for hopper cars to ship their own grain directly to a destination of their choice — typically a terminal elevator, processor, or export facility.
Producer cars are allocated through a weekly application process through the Canadian Grain Commission’s online system. Applicants must have a confirmed sale and destination before applying. Applications specify the shipping week, the station, and the grade and quantity of grain. The CGC manages the allocation and coordinates car placement with CN and CPKC through their respective producer car programs. CN’s loading sites for producer cars are listed by province on the CGC website; CPKC’s sites are similarly listed.
The producer car program provides the most direct form of basis improvement available to Prairie producers, because it eliminates the elevator margin that is embedded in country elevator cash bids. A producer who ships a producer car to a terminal elevator and sells directly to the terminal is capturing the full terminal bid rather than the country elevator bid minus elevator spread. In periods when country elevator basis is wide — which often coincides with poor rail car supply — the economic incentive to pursue a producer car allocation is highest, precisely when producer car availability is most constrained.
Producer cars are not administratively simple. The producer must arrange loading logistics, complete the bill of lading accurately, and release the car to the railway in a timely manner. Cars not loaded on schedule are pulled empty and the producer is charged a penalty fee. For producers without regular experience in the program, the first few producer car applications carry a meaningful administrative learning curve. However, for operations with the grain volume to justify the effort, direct rail access through the producer car program is a genuine margin improvement opportunity that more Prairie producers use than is commonly discussed in mainstream agricultural media.
The producer car program applies to movements in the regulated Western grain system — meaning it operates within the MRE framework, and the car allocations are subject to the same corridor and seasonality constraints as commercial elevator shipments. During periods of tight car supply, producer car allocations may be limited by the same constraints that restrict elevator car orders.
Regulatory Tools When Service Fails: Level of Service and Shipper Remedies
The Canada Transportation Act provides Prairie grain shippers with specific regulatory remedies when railway service falls below statutory requirements. These tools are underused by individual producers and smaller elevator operators, partly because the complaint process requires documentation and administrative effort, and partly because awareness of the specific provisions is limited outside of the grain trade associations that routinely engage with the CTA.
The level of service obligation requires CN and CPKC to provide adequate and suitable accommodation for the traffic offered to them. When a railway consistently fails to fulfill car orders, delays shipments unreasonably, or provides service that falls materially below what a shipper requires, the shipper can file a level of service complaint with the CTA. The CTA can order the railway to take specific remedial action and, in some cases, award damages. Level of service complaints are most effective when supported by detailed documentation of car order requests, fulfilment rates, and the commercial impact of service failures — which is why the Ag Transport Coalition’s weekly tracking data is not just informational but also serves as a foundation for complaint documentation.
Arbitration under the Canada Transportation Act is available for disputes over railway rates. When a shipper believes the rate it is being charged is unreasonable, it can trigger final offer arbitration — a process in which both the shipper and the railway submit their best offer and an arbitrator selects one or the other. The winner-take-all structure incentivizes both parties to submit reasonable offers rather than extreme positions. Final offer arbitration has been used by grain shippers as a rate discipline tool, though it requires significant commercial and legal resources and is more typically used by elevator companies or processors than by individual producers.
The interswitching regulations — currently under CTA review — provide shippers within specified zones near railway interchange points the right to direct their traffic to a competing carrier. Expanded interswitching zones increase competitive pressure on the dominant railway in a given region, which can moderate rates and improve service quality through the threat of diversion. The interswitching review underway in 2025-26 will determine whether these zones are expanded, maintained, or contracted — an outcome with direct relevance to rail competition across Prairie corridors.
The 2025-26 Crop Year: Record Supply Meets System Demand
The 2025 Prairie crop was a record in production terms — AAFC estimates total principal field crops production rose approximately 10 per cent year-over-year, with canola setting a new record at 21.8 million tonnes and wheat production reaching 32.8 million tonnes on record yields. This record supply is what is moving through the transportation system in the 2025-26 crop year, and it is what produced the record volumes at Vancouver, the record CPKC January performance, and the elevated MRE utilization.
Record crops create record transportation demand. The 49 million tonnes recorded in the 2024-25 CTA determination was substantially driven by the 2024 crop; the 2025-26 system will be stressed by the 2025 record crop moving out simultaneously with the 2026 seeding preparation period. This timing creates a double demand load on system capacity: old crop movement pressure from the 2025 harvest competing with logistics and supply chain requirements for the 2026 seeding season.
For the 2026-27 crop year — which begins August 1, 2026 — the volume forecast depends on what the 2026 crop produces. AAFC’s April 2026 outlook assumes a return to trend yields, which would reduce canola production from the 2025 record of 21.8 million tonnes to approximately 18 to 19 million tonnes under average conditions. A return to trend production after a record year typically provides some relief to the transportation system’s peak-season demand, because total volume to move is lower. However, if the 2026 crop comes in near or above trend — supported by adequate moisture in key production areas — the system will face another high-volume year with limited additional infrastructure capacity relative to 2025-26.
The one variable that could materially change system demand in 2026-27 is crop mix. The fertilizer price shock and seeding delays discussed in the Fertilizer & Input Costs and Agroclimate Outlook pillars may push some acreage toward lower-input crops — pulses, forages, or reduced-input cereals — that carry different transportation profiles than high-volume canola or spring wheat shipments. Pulses, for example, frequently move by container rather than bulk hopper, routing through the container terminals at Vancouver rather than the bulk grain terminals. A meaningful shift in crop mix toward containers would change the system’s demand distribution between bulk and container rail and port infrastructure.
What to Watch in Grain Transportation Through 2026
The Ag Transport Coalition publishes weekly car order fulfilment data for both CN and CPKC. This is the most current, operationally relevant indicator of system performance available without a subscription. Producers and elevator operators who are planning grain movement through the summer and fall should be tracking this data weekly, particularly through the July-to-October period when the new crop harvest creates peak system demand. A pattern of fulfilment declining below 80 per cent on either railway before the 2026 harvest is complete signals that the system is moving into stress territory.
The Second Narrows bridge remains the single most consequential physical risk point in the Canadian grain export system. Any extended mechanical failure, seismic event, or structural emergency at the bridge during the fall harvest export window would have immediate and severe consequences for basis at Prairie elevators. Producers holding unpriced grain through the fall should be aware of this risk as one of the low-probability, high-consequence scenarios that grain price risk management should account for.
The Iran conflict trajectory matters for marine freight rates and shipping insurance availability on global bulk carrier routes. A resolution that reopens the Strait of Hormuz would release vessel capacity back into the global bulk shipping market, easing Panamax freight rates and reducing the freight cost component embedded in Prairie grain basis. This would be a basis-positive development for Prairie producers — the opposite of the basis-widening pressure that higher ocean freight rates create.
The CTA’s interswitching review is an ongoing regulatory process with potential to reshape competition on Prairie rail corridors. Expanded interswitching zones would benefit shippers in newly eligible corridors through rate competition; a contraction of zones would reduce that leverage. The CTA has committed to completing this review in 2025-26, and its outcome — expected before the end of the current crop year — will be relevant to any Prairie producer or elevator operator within proximity of railway interchange points.
Statistics Canada’s June 30, 2026 seeded area survey will establish the production baseline for the 2026 crop and, by extension, the volume of grain that the transportation system will be asked to move starting in August. A large 2026 crop would maintain high system demand through 2026-27; a significantly reduced crop would ease demand pressure and potentially improve car supply and basis for producers holding old crop into the summer.
