Facebook marketplace for used books and used goods in general. Lots of good quality basically new stuff on there for cheap. I guess because so many Canadians just buy stuff without thinking and then it piles up and they need to make space.

Some neighbourhoods also have some boxes on posts (not sure what they’re called, they resemble mailboxes) where people can take and give away books for free as well.

You can also type ‘bookstores’ in google maps and seeing what local stores will come up.
