Space will be available by reservation, which is available online on the website of your chosen location, by telephone or in-person, Mayor Plante told MTL Blog.
The mayor says that people can come to work, study or simply to use the internet.
She acknowledged the fact that not everyone has a stable internet connection or can easily study/work from home.
Montrealers will also be able to reserve books, but browsing the shelves won't be possible just yet.
"We're here to facilitate your lives during times that aren't always easy," Plante said.
