It's a big weekend for road closures in Toronto with the return of Open Streets on August 21. The pedestrian celebration and recreational festival will shut down a major stretch of both Yonge and Bloor streets on Sunday, which should be on your radar. Fortunately, there are no scheduled TTC subway closures to add to the navigational challenge.

Open Streets will shut down Yonge Street between Bloor Street Queen and Bloor Street between Dufferin and Parliament on Sunday between 10 a.m. and 2 p.m., but give a little leeway on either side for maintenance crew to remove barriers.

In addition to Open Streets, there are two street festivals that will snarl traffic in their respective areas. The annual Chinatown Festival will close the southbound lanes of Spadina Ave. between St. Andrew and Sullivan streets from 9:00 a.m. Saturday to 11 p.m. Sunday. TTC service will operate as normal.

Further uptown, Taste of Manila will close down Bathurst Street between Wilson and Laurelcrest avenues from early Saturday to 8 p.m. on Sunday. Try to avoid using the Bathurst exit from the 401 this weekend even if you'r headed to the area.

Noteworthy events that don't feature scheduled closures but that will nevertheless cause congestion are the CNE and the Sail-In Cinema. And, of course, there's plenty of ongoing construction to be aware of. For a full list of road restrictions and closures, check the official city of Toronto map.
