Diversion info for the 501/301 Queen service has been added.

On the weekend of October 16-18, the Toronto Waterfront Marathon will cause extensive disruption to transit service downtown. This is on a scale we have not seen for previous events, and begs the question of just how serious Toronto is about maintaining transit service even when promoting the TTC as the best way to get to the event.

Marathon closures will also affect motorists. See the Race Weekend Schedule and scroll down to the detailed list of road closures.

There are two races: a 5k run on Saturday, October 17 and a full/half marathon on Sunday, October 18.

Transit service will be suspended on many routes including the creation of some “transit deserts” through the combined effect of overlapping changes. This article consolidates information in many TTC service notices. Some of these have changed while I built this article. Readers are advised to check for further updates on their day of travel on the TTC’s site.

Although it is listed on the TTC’s Marathon Page, there are no details for the 501/301 Queen Streetcar service changes. If they appear, I will update this article.

Maps and a table showing the service changes are in the next section following the “more” break.
