There are two great ones in downtown Montreal, apparently owned by some cool Russian people. https://www.anticafe.org/

They are often the place of Russian language and culture events, which is how I heard of them.

I love the concept, but personally having to sign in to track time seems less "streamlined" to me than just buying a drink, so I didn't have a reason to go back, but maybe if the first hour was free in exchange for installing an app, it would be worth it. (I also don't hang out in cafes or coworking spaces much these days).
