LRTs Face Winter Weather Challenges
Winter storms have long been a challenge for transit systems across Canada, and this year, the light-rail transit (LRT) systems in Toronto, Montreal, and Ottawa faced significant disruptions following heavy overnight snowfall. The disruptions led commuters to question whether these newer LRT systems were adequately designed to withstand harsh Canadian winters. With the country’s infamous snowstorms and freezing conditions, LRT systems are expected to operate smoothly despite these seasonal challenges. However, recent events have raised doubts about their reliability during winter months, particularly as new lines continue to face issues with snow removal, freezing rain, and icy tracks.
On January 15, 2026, commuters in all three cities—Toronto, Montreal, and Ottawa—found themselves delayed and frustrated as LRT services were suspended or reduced due to snow buildup, technical malfunctions, and other winter-related issues. This article examines the recent disruptions, the specific design challenges faced by these LRT systems, and whether they can be expected to handle the harsh winters that are a hallmark of Canadian weather.
Recent Disruptions: A Common Theme Across Three Cities
Thursday morning, January 15, 2026, saw disruptions to all three cities’ LRT services. In Montreal, the Réseau Express Métropolitain (REM) saw significant delays, particularly on the Deux-Montagnes line, due to freezing drizzle and snow buildup on power lines. In Toronto, the Finch West LRT, which opened only a few months earlier, experienced operational issues, with service slowed by snow accumulation on the tracks and malfunctioning switches. Ottawa’s LRT Line 2 also suffered delays, with a switch failure caused by snow accumulation forcing service suspensions between Leitrim and South Keys stations. Despite efforts to provide replacement bus services, the delays impacted thousands of commuters, many of whom were already familiar with the winter-related struggles of transit systems in their cities.
These disruptions have raised questions about the LRT systems’ ability to function consistently during Canadian winters. While snow-related interruptions are common for most transit systems, many experts argue that the newer LRT designs should have been better equipped to handle such challenges.
The REM and the Challenges of Montreal’s Winter Weather
Montreal’s REM line, which launched in 2023, is one of the newest additions to the city’s transit infrastructure. While the REM has generally improved since its initial struggles, the snowstorm on January 15 exposed several weaknesses in its design. Montreal commuters, like David St-Pierre from Brossard, found themselves waiting up to 50 minutes for a train due to delays on the Deux-Montagnes line. St-Pierre, who was optimistic about the new system, was disappointed with the disruption.
The REM line runs on above-ground tracks and, as with many other LRT systems, is susceptible to weather-related issues such as snow and ice buildup. However, critics argue that Montreal’s new LRT system should have been better prepared for the winter conditions typical of the region. Dr. Ahmed El-Geneidy, a professor at McGill University, noted that heavier trains, such as diesel-powered suburban trains, tend to perform better in snow due to their greater weight and engine power. By comparison, the REM, which is designed to be more energy-efficient and environmentally friendly, struggles to cope with the challenges posed by extreme weather conditions.
The current winter issues with the REM have led to discussions about the adequacy of snow removal mechanisms, especially considering the harsh winters Montreal experiences. Experts are calling for the introduction of better snow-clearing systems or enhanced track heating mechanisms to mitigate such problems moving forward.
Toronto’s Finch West LRT: Struggling to Keep Pace with Winter
Toronto’s Finch West LRT, which opened in late 2025, was also plagued by disruptions on January 15. The LRT, which replaces the former bus routes along Finch Avenue, has faced multiple operational challenges since its launch. The system, which was originally designed to run smoothly and quickly, encountered issues with the technology used to melt ice and snow along the tracks. Unfortunately, the snow-melting technology used on Finch West LRT is the same system that failed on Ottawa’s LRT lines in previous winters.
Steve Munro, a Toronto transit advocate, points out that the Finch West LRT is a perfect example of how testing and preparation for Canadian winters should be prioritized. According to Munro, the LRT’s design flaws, including inefficient snow removal systems and unreliable switches, have led to disruptions that were entirely avoidable with more thorough testing before the launch. Munro, who has extensively studied Toronto’s transit system, argues that the lack of preparation for winter conditions is a significant oversight, especially given the city’s history of heavy snowfalls and freezing temperatures.
The failure of the Finch West LRT’s snow-removal technology and its unreliable service are growing concerns for commuters like Katherine Bignell-Jones, who finds the service less efficient than the buses it replaced. As more people opt to stay home or seek alternative routes to avoid the “transit mess,” the long-term viability of this LRT system is being questioned.
Ottawa’s LRT System: A Persistent Problem with Winter
Ottawa’s LRT system, which launched in 2019, has faced multiple issues related to winter weather since its inception. In particular, Line 1 has experienced several service interruptions due to freezing rain, ice buildup on overhead wires, and damaged power systems. The city’s LRT lines, particularly Line 2, which launched in 2025, were expected to function better during winter, but they too have been plagued by snow-related disruptions. On January 15, Line 2 was temporarily suspended between Leitrim and South Keys stations due to snow accumulation on the switches, highlighting the system’s vulnerability during extreme winter weather.
Ottawa’s transit agency, OC Transpo, has already taken steps to improve winter operations, but the ongoing challenges point to the need for further investments in snow and ice management technologies. In particular, the city’s reliance on traditional snow removal methods has proven to be inadequate for the demands of a modern LRT system. As with Montreal and Toronto, Ottawa’s LRT systems may need to explore alternative solutions, such as heated tracks or better snow-clearing equipment, to avoid future disruptions.
Lessons Learned: Can LRT Systems Handle Canadian Winters?
The winter-related disruptions faced by the REM, Finch West LRT, and Ottawa’s LRT lines on January 15 serve as a reminder that Canadian winters present unique challenges for urban transit systems. While LRT systems are often seen as a cost-effective alternative to more expensive underground subway lines, they come with their own set of design challenges, particularly when it comes to snow and ice management.
Experts argue that winter weather preparedness should have been a top priority during the planning and development of these systems. While LRTs are more environmentally friendly and energy-efficient than traditional trains, their above-ground nature makes them more vulnerable to weather disruptions. Cities like Montreal, Toronto, and Ottawa must now weigh the trade-offs between cost-effective public transit and the need for robust winterization solutions.
For now, commuters in these cities are left to contend with frequent delays and disruptions, while transit agencies scramble to find solutions. With Canadian winters expected to continue for the foreseeable future, ensuring that LRT systems are designed to withstand these conditions is crucial to maintaining reliable and efficient public transportation.
The Road Ahead for LRTs in Canada
As winter continues to test the limits of Canada’s LRT systems, the cities of Montreal, Toronto, and Ottawa must make critical decisions about how to enhance the resilience of these systems in the face of harsh weather conditions. Investing in better snow removal technology, track heating systems, and other winterization measures could help improve service reliability and prevent future disruptions. Only time will tell if these cities can adapt their LRT systems to the challenges posed by Canadian winters, but one thing is certain—preparation for winter weather must become a top priority if these transit systems are to succeed in the long run.
