Rail Freight Delays in Canada: CN and CPKC Under the Maritime Lens

Rail freight delays involving CN and CPKC are disrupting Canada’s maritime supply chain. Explore the causes, impacts on port operations, and future strategies for improving multimodal logistics.

Why Rail Freight Delays Matter in Modern Maritime Operations

Ports are the beating hearts of maritime logistics—but they are only as efficient as the railways feeding them. In Canada, two Class I railways—Canadian National Railway (CN) and Canadian Pacific Kansas City (CPKC)—form the backbone of inland cargo movement from major ports like Vancouver, Prince Rupert, and Montreal to the Prairie provinces, the U.S. Midwest, and beyond.

Yet, over the past few years, rail freight delays have become a recurring bottleneck. From extreme weather events to labor disputes and infrastructure constraints, delayed rail service has disrupted everything from containerized cargo flows to bulk shipments of grain and fertilizer.

For maritime stakeholders, this is not a landlocked problem. Delays on the rails quickly escalate into vessel demurrage, cargo backlog, container shortages, and increased operational costs at port terminals.

This guide unpacks the structural, operational, and policy issues behind CN and CPKC rail freight delays—and their cascading impact on Canada’s maritime economy.

Canada’s Rail Network: A Maritime Connection

CN and CPKC: National Lifelines

  • Canadian National (CN) operates the largest rail network in Canada, spanning from Halifax to Vancouver, with key intermodal hubs in Toronto, Winnipeg, and Edmonton.

  • CPKC, the product of the 2023 merger between Canadian Pacific and Kansas City Southern, forms North America’s only Canada-to-Mexico single-line railway—a potential game changer for north-south trade.

Together, these two companies move over $250 billion in freight annually and are critical to the port-to-door supply chain for thousands of Canadian importers and exporters.

Interdependence with Ports

Key port-rail connections include:

  • Port of Vancouver: Over 60% of containers are moved inland via rail, mostly through CN and CPKC.

  • Port of Prince Rupert: Known for its direct CN rail access, it offers the fastest trans-Pacific route to Chicago.

  • Port of Montreal: Connected via CN and CPKC to Toronto, Detroit, and Chicago.

Key Drivers Behind CN/CPKC Rail Freight Delays

1. Extreme Weather and Climate Events

From wildfires in British Columbia to floods in Manitoba, Canada’s rail corridors have faced historic climate disruptions.

Case in Point: In November 2021, torrential rain and landslides shut down CN and CP rail lines to the Port of Vancouver. This resulted in:

  • Over 1,000 containers stranded per day.

  • Port dwell times exceeding 12 days.

  • Estimated economic losses of over CAD 500 million (Transport Canada).

2. Labor Disruptions

Labor shortages and union disputes have plagued both CN and CPKC in recent years. In 2019, a CN conductors’ strike halted operations for eight days, halting the movement of 100,000+ rail cars.

CPKC has also faced contract disputes with engineers, while downstream issues at container terminals—such as ILWU strikes—have also impacted rail productivity.

3. Infrastructure Bottlenecks

Despite recent investments, rail capacity remains constrained by:

  • Single-track limitations in mountainous regions.

  • Congestion in key yards (e.g., Toronto, Edmonton).

  • Lack of real-time cargo visibility between rail and marine terminals.

These constraints reduce train velocity and increase dwell times at port intermodal facilities.

4. Increased Trade Volumes Post-COVID

Canada’s ports saw record container volumes in 2021–2022 as global shipping rebounded. However, rail infrastructure and scheduling struggled to keep pace, leading to:

  • Longer wait times for vessel berthing.

  • Empty container imbalances.

  • Missed delivery windows across inland networks.

Real-World Case Studies

Case Study: Port of Vancouver Blockage (2021)

In a rare weather convergence, a series of landslides destroyed CN and CP tracks through the Fraser Valley. The result:

  • 12-day port rail outage.

  • Vessel anchorage peaked at 50 ships.

  • Auto parts, grains, and e-commerce shipments were delayed across North America.

The event highlighted the need for climate-resilient rail infrastructure and emergency rerouting capabilities.

Case Study: Prince Rupert CN Congestion (2022)

Prince Rupert’s high-efficiency intermodal terminal was backed up for weeks when CN experienced a locomotive shortage during peak shipping season. The port’s lack of alternate rail providers meant:

  • Containers piled up at terminal yards.

  • Shippers rerouted cargo to U.S. West Coast ports.

  • Exporters faced penalties for missed sailing schedules.

Challenges and Solutions

Challenge: Lack of Rail Redundancy

With only two Class I operators, Canada’s rail system lacks redundancy in many regions—especially on routes to Vancouver and Prince Rupert.

Solution: Government-backed incentives for short-line rail expansion, greater interoperability between CN/CPKC corridors, and port investments in multi-rail access can boost resilience.

Challenge: Disconnect Between Marine and Rail Planning

Port terminals and railways often operate on different optimization models—ports prioritize ship schedules; railways prioritize asset utilization.

Solution: Implementation of Port Community Systems (PCS) and Rail Scheduling APIs can allow real-time coordination between shipping lines, port terminals, and railway companies.

Challenge: Inadequate Real-Time Cargo Visibility

Freight forwarders and shippers often lack visibility into rail delays, leading to downstream logistics chaos.

Solution: Enhanced IoT rail tracking, digitized bills of lading, and integration with Global Navigation Satellite Systems (GNSS) can provide end-to-end transparency.

Future Outlook: Strategic Investments and Policy Reforms

Infrastructure Modernization

Both CN and CPKC have pledged over $4 billion in capital investments (2023–2026), including:

  • Double-tracking through key bottlenecks.

  • Upgrading intermodal yards (e.g., Milton Logistics Hub).

  • Enhancing locomotive fleets with low-emission hybrid engines.

Digital Transformation

CPKC and CN are embracing data analytics and AI-driven dispatching to improve train scheduling, optimize railcar loads, and minimize idle times.

Case in Point: CN’s deployment of Precision Scheduled Railroading (PSR) has improved car velocity by 20%, though critics argue it prioritizes cost-cutting over capacity building.

Policy Support from Ottawa

Transport Canada’s 2024 Supply Chain Strategy recommends:

  • A national rail resiliency framework.

  • Climate adaptation for key corridors.

  • Performance-based metrics for railway service reliability.

If implemented, these reforms could bridge the gap between rail and port systems.

Frequently Asked Questions (FAQ)

Q1: Why are CN and CPKC delays such a big issue for ports?

Because 60–70% of port cargo moves by rail. Delays ripple across the supply chain, leading to vessel delays, container congestion, and customer dissatisfaction.

Q2: Which port is most affected by rail delays?

Port of Vancouver due to its reliance on mountain corridor rail access and high import volumes.

Q3: Are these delays seasonal?

Many are, particularly due to winter storms and wildfires. However, labor strikes and capacity mismatches also occur year-round.

Q4: Is rail more cost-effective than trucking?

Generally, yes—especially for long-haul inland transport. But delays erode cost savings through inventory shortages and demurrage fees.

Q5: What’s being done to fix the problem?

Rail operators are investing in infrastructure, automation, and AI. Federal and provincial governments are working on resiliency strategies.

Q6: Can marine terminals do more to help?

Yes—terminals can optimize container staging, share real-time data with rail partners, and enhance buffer yard capacity.

Q7: How do these delays affect international trade?

They can force shippers to reroute cargo via U.S. ports or airfreight, increase insurance premiums, and damage Canada’s reputation as a reliable logistics hub.

Conclusion

Rail freight delays involving CN and CPKC are not merely land-based inconveniences—they are fundamental disruptors of Canada’s maritime supply chain. From climate events to infrastructure bottlenecks and planning disconnects, the challenges are complex—but not unsolvable.

By embracing digital coordination, infrastructure investment, and smarter policy, Canada can strengthen the link between its ports and railways—ensuring that the country remains globally competitive in the race for trade efficiency.

As maritime logistics becomes increasingly intermodal, understanding and addressing rail freight dynamics is essential for every stakeholder navigating the Canadian trade corridor.
