Finch West LRT underground debate highlights need for all-weather rapid transit
TORONTO — Two months after opening, the Finch West LRT (Line 6) has delivered an important lesson for Toronto’s transit future — and it’s one the city cannot afford to ignore.
The line has improved access across northwest Toronto. It has replaced one of the busiest bus routes in the city. And it has brought long-overdue investment to transit-dependent communities.
But it has also exposed a deeper issue:
Building transit is not enough — it must be built to perform in real-world conditions.
The Finch Lesson
The biggest challenge facing the Finch West LRT has not been ridership or infrastructure quality.
It’s performance.
In its first month, riders have experienced slower-than-expected travel times, with trains stopping at red lights and navigating intersections in ways that limit the benefits of a dedicated right-of-way. The city is now working to improve signal priority — a necessary step — but one that highlights a broader limitation.
Surface transit, even when separated from traffic lanes, still operates within the road network.
And that comes with trade-offs.
The Signal Priority Reality
At launch, the Finch West LRT operated with conditional signal priority, meaning trains only received priority at intersections when they were behind schedule.
In practice, this resulted in trains frequently stopping at traffic lights — undermining the idea of continuous, rapid service.
The City of Toronto has since acknowledged the issue and is now moving to implement more aggressive signal priority across the corridor.
These improvements will help.
But they also reinforce a key point:
Signal priority is a fix — not a foundation.
Winter Reality: Transit Must Work in Snow
Another issue emerging early is how the line performs in winter conditions.
Heavy snowfall has already raised concerns about track conditions, as snow accumulation can interfere with operations, slow down service, and require ongoing maintenance to keep the line running smoothly.
Unlike underground systems, surface LRT lines are fully exposed to the elements.
In a city like Toronto — where winter conditions can last for months — that exposure matters.
Subways operate regardless of weather.
Surface lines must constantly adapt to it.
In a country where winter is a guarantee, transit systems must be built to perform in all conditions — not just ideal ones.
Why Underground Works Better
Toronto already has a clear example of a more reliable model:
the underground sections of the Eglinton Crosstown (Line 5).
Where Line 5 runs underground:
- Trains move without interruption
- Travel times are consistent
- Service is unaffected by traffic or weather
In those sections, transit performs at its highest level — fast, predictable, and resilient.
That’s the standard riders expect.
Surface LRT Has Limits
Surface LRT still plays an important role. It is more affordable to build and can expand transit coverage more quickly.
But its limitations are now clear:
- Intersections slow service
- Traffic signals interrupt flow
- Weather conditions impact operations
In lower-demand corridors, these trade-offs may be acceptable.
But on major transit routes — like Finch — they become harder to justify.
Don’t Repeat the Mistake
The Finch West LRT is not a failure. It’s a case study.
It shows what happens when a high-demand corridor receives better transit — but not the most resilient version of it.
The real risk is not what has been built.
It’s what could be built next.
Toronto is planning future transit projects, including:
- The Eglinton East LRT
- The Waterfront East LRT
- Future LRT corridors across the city
If these projects rely too heavily on surface designs, the same challenges will follow — slower speeds, operational compromises, and weather-related disruptions.
Build Once. Build Right.
Transit infrastructure lasts for generations.
The decisions made today will define how Toronto moves for decades. That means prioritizing systems that deliver:
- Consistent travel times
- Full reliability
- Resilience in all seasons
In many cases, that means building underground — even if it requires greater upfront investment.
Because the cost of doing it halfway is paid every day by riders.
The Bigger Picture
The Finch West LRT has improved transit access for thousands of riders.
But it has also clarified what the next phase of transit planning must focus on:
Not just expanding the network
But building it to its highest possible standard
Because in a growing city — and a winter city — reliability is everything.
