If you're a transit commuter in and around the city, make sure to plan ahead this weekend for a couple of very significant closures. Both the GO Train Lakeshore East line and parts of the TTC subway line 1 will be shutting down, and these Toronto transit closures are due to some significant upgrades to the system. If you rely heavily on transit taking you around Toronto and the GTA, it's time to familiarize yourself with the alternatives you can take to get you where you need to be. 

It's not particularly rare for there to be some kind of transit disruption over a weekend in Toronto, but the scale of this weekend's closures might make this weekend a little tougher than normal.

In fact, in what Metrolinx is calling a "rare move", the entire Lakeshore East line will be shut down for most rail traffic, for infrastructure upgrades. According to Metrolinx, this upgrade is part of renovations aimed at adding "two decades onto the lifespan of a major bridge."

"Having barely any trains running on this important, busy line is a rare event – one that's being done to support a number of important projects that will strengthen the corridor," says Metrolinx spokesperson Nitish Bissonauth.

The projects Bissonauth mentions include major bridge upgrades to the Danforth Bridge between Warden Avenue and Birchmount Road, upgrading two rail crossings at Beechgrove Drive in Scarborough and Rodd Avenue in Pickering. There will also be signal upgrades at Ajax GO and Metrolinx is replacing old railway ties and track elevations from Pickering GO to Guildwood GO Station.

But don't worry, as if you plan to go to downtown Toronto this weekend from Durham-region cities like Oshawa, Whitby, Ajax, or Pickering, Metrolinx says the Route 90B GO buses will be running from those stations to Union station.

If you're coming from the West end heading east, you'll have to take the same bus from Union to any of the Durham stations.

Now, as for the TTC, there will be some major closures on line 1 from St. Clair to Union starting on Saturday, October 26, until 8 p.m. for a signal system installation.

On Sunday, October 27, there will also be no subway service on Line 1 from Lawrence to Bloor-Yonge stations for the same signal system installation. Summerhill Station will be closed on both Saturday and Sunday.

This is all in an effort to make your commute as smooth as possible in the future, so there's method to the madness. It might be best to prepare for a little bit of weekend frustration, though, particularly with Halloween around the corner.

So, this weekend you should make sure to give yourself a few extra minutes so you can avoid arriving late to wherever you need to be.
