This post updates a table of TTC delay stats for 6 Finch West published here about a month ago. The breakdown of delays by cause was recently refreshed by the TTC to include January 2026. I have included the December stats for comparison.
Bearing in mind that January included a full month’s operation, the number of delays declined proportionately, but the length of delays did not change much compared to December.
- January had 386 delays compared to 350 in December with a big jump (11 to 35) in weather-related incidents.
- The total delay minutes in January rose by about one third compared to December, again due to weather (40 minutes delay versus 1069).
Equipment problems of various kinds continue with a disconcerting preponderance of “other”.
Of concern is a doubling of the delays due to “no equipment available” indicating that Mosaic is not able to reliably field 15 of the 18 cars in the fleet for service. This has implications for future service growth other than whatever can be achieved with faster operation and, hence, shorter headways.
Operator overspeed incidents are down by half implying a growing familiarity with the line and, possibly, improvement in the speed profile enforced by the control system.
Changes to signal timings began on Finch recently, but as the TTC does not have any tracking data for the new lines 5 and 6, it will be difficult to review the ongoing benefits, and the chance for a “before” snapshot has passed.
The full table of delay counts and times for December 7, 2025 to January 31, 2026, follows the “more” break.

Are the Citadis Spirit vehicles on Line 6 less reliable than the Flexity Freedom trains on Line 5? We hear very little about problems on Line 5.
Steve: Yes, based on the rarity of delays due to “mechanical problems” on Line 5, I would have to say those vehicles are better. In a month we will see delay logs for Line 5 and be able to put hard numbers to this.

Delays classed as ‘Brakes’, ‘HVAC’, and ‘Door Problems’ seem to have increased quite a bit, not just in relative terms but in absolute numbers. That’s a little worrying.

Btw line 5 does have train tracking available especially the next train arrival is publicly available on the TTC website. Meanwhile line 6 have started earlier still doesn’t have live tracking of any sort not even next arrival publicly.
Steve: But it’s still not available as a public feed nor in archival form.

I wonder if that might actually be a beneficial side effect of the long delayed opening of Line 5 rather than the actual reliability of the vehicles. Basically, they had more time to catch and correct the bugs with the Flexity fleet before opening day.
Steve: Both fleets were on property for years before opening. It is not credible that problems for both fleets were not found, debugged and fixed before opening day. Whether this is a question of design, manufacturing, testing or maintenance problems remains a mystery.
