Scheduled TTC subway closures for 2017 are extensive. So if you're a weekend commuter, get ready to feel the pain. There are 35 closures scheduled this year, many of which will affect Line 1, the busiest in the city's system.

In fairness, that number is actually down three closures compared to 2016, but the fact remains that regular subway shutdowns have become a part of life in Toronto these days.

On the bright side, all the work being done on Line 1 will pave the way for a new automatic signal system to be rolled out at the end of the year that will allow trains to run closer together at higher speeds, thus helping to reduce crowding during the morning and afternoon commutes.

The TTC will try to manage the 11 scheduled closures between St. George and Downsview with a different system than it's used in the past. It will only run shuttle buses between Lawrence West and Downsview during these shutdowns.

Because of various road construction projects spanning the stretch to the south, the plan instead is to increase east/west routes connecting the Yonge Line (which will be open) to Spadina section of Line 1. Theoretically, that will reduce the time people spend on buses during the closures.

The closure plan is being presented to the TTC board on January 18. The first of the shutdowns follows next weekend, January 21-22, with Line 1 closed for ATC signal work between St. George and Downsview.

There is only one closure scheduled in each of January and February. Mercifully, the closures don't reach their peak until the weather warms up. There's a scheduled closure every weekend between April and August this year.
