Stats from 2014 to 2019

Toronto Subway Delays

Have you ever wondered why the Toronto subway has so many delays?

I analyzed data on TTC subway delays for the last six years (from 2014 to 2019) and turned it into meaningful stats with explanations.

The city of Toronto provides all information on Toronto Subway Delays at

"Back where we belong as number one in North America. A huge amount of effort has been expended, and a huge amount has been achieved. The TTC is now cleaner, friendlier, more punctual, and more reliable."

– TTC CEO Andy Byford

🛑 Avoid these times if you don't want to get stuck in the subway.

Taking the subway in Toronto can be unpredictable. You never know how long it will take to get from one place to another. By avoiding these times, you can be on time and avoid annoying delays on the subway.

1. Thursday - 4 PM to 8 PM

Thursdays are the worst for the TTC subway. The chances of getting stuck are high, so try to avoid these evening times.

2. Friday - 4 PM to 8 PM

Avoid taking the subway in the evening on Fridays, especially from 4 PM to 8 PM. The delays can be quite frustrating.

3. Tuesday - 6 AM to 10 AM

There's a little difference between Tuesdays and Fridays. Morning rides can make you late, so plan ahead!

4. Wednesday - 6 AM and 10 AM

Wednesdays are not much better, with delays similar to Monday and Tuesday. It's best to avoid the subway during these morning hours.

5. Monday - 6 AM to 10 AM

On Mondays, the subway is still quite busy, but the chances of getting stuck are a bit lower than on other days.

6. Saturday - 8 PM to 12 AM

On weekends, the subway is less crowded. With fewer people traveling to work, you have a better chance of being on time for your evening plans.

7. Sunday - 8 AM to 12 PM

On Sundays, the likelihood of delays drops to about 10%. Most people prefer walking shorter distances, so the subway is less busy.

🚇 Speed control problems cause up to 30% of all TTC subway delays.

Almost 45% of delays come from the issues listed below. Altogether, there are over 100 possible reasons a subway train might stop.

💨 Miscellaneous speed control – 15,5%

Speed control issues happen when there's a problem with the speed control system. This triggers the emergency brake, and the train can't move until transit control gives the okay to reset it and continue. These problems make up 15.5% of the delays.

👤 Operator over speeding – 11.3%

Right now, Toronto subway trains are driven by operators, and human factor often leads to problems with speed control, causing 11.3% of delays. The TTC has a plan to switch to automated trains in 2022, which should help solve this issue.

🆘 Alarm activated (no trouble found) – 6.7%

Sometimes, people press the alarm button on the subway even when there's no real emergency. In Toronto, this happens quite a bit, causing trains to stop often for no serious reason.

🚑 Injured or ill customer (transported) – 6.4%

Some travelers fall ill during their subway ride. Usually, these health issues are triggered by staying in a closed, stuffy, overcrowded place like a subway car.

🔘 Other Issues – 4.2%

There are lots of other problems that cause subway delays. For example, fires or smoke on the tracks, doors getting stuck or blocked, unauthorized people on the tracks, or even assaults involving passengers. These issues, though varied, add up to 4.2% of all delays.

How long does it take to resolve an issue in the Toronto subway?

Have you ever wondered how long it takes to fix a problem on the Toronto subway? It often feels like ages before things get moving again after a delay. Mornings can seem especially slow when you're trying to get to work. But according to the TTC, 97.4% of issues are actually resolved in under 15 minutes.

Do seasons affect TTC performance?

Yes, the seasons can mess with Toronto's subway system too. In this part, we look at the numbers for all TTC subway problems that took more than a minute to fix per season.

The average number of cases per season.


Delays in the subway cause a "Domino Effect" where one problem leads to another before the first issue is fixed. This makes it vital to resolve all problems quickly and only hold trains in rare cases.

The TTC has a lot of work to do to improve the Toronto subway service and justify the $3.25 fare, which is among the highest in the world.

I didn't include stats about the Presto Card, which is now the only way to pay in the subway. Sadly, the TTC doesn't share data on how often the Presto card failed or didn't work properly in 2019 and early 2020. If you want to see the "wonderful" experience with Presto, check out their ratings on the App Store or Google Play.
