Updated August 6, 2020

After Mid-March, festivals and parades were cancelled because of COVID-19. Everything that would have taken place in summer 2020 was cancelled.

Some streets have been fully pedestrianized all summer, including Mont-Royal between Park and Fullum, the usual segment of Ste-Catherine through the Village, part of Wellington Street, and parts of Ste-Catherine West as well. These are not street fairs per se but there are terrasses. For the moment, the density of crowds brought by popular street fairs is probably off till next year.

As of the second week of August, gatherings of 250 people or less are permitted in Quebec, with pandemic measures in place. Some festivals have been revived (see list) but it seems unlikely the street fair schedule will return to its conventional pattern this summer.

Most dates below are still from 2019. Most seasons have followed a similar pattern with occasional novelties and changes from time to time, but it’s impossible to know how the pattern will change in future. I’m leaving this content here with hopes for 2021.
