I’m in Canada

(You’ll notice that this is the same as the post about the USA. EXMNA are North America focused, we swear we’re not confusing you with Americas! You’re too nice

By far and by large, the best community to go to in Canada is EXMNA, which started off Reddit (just like the London/UK communities). They have two sides to them, an outward facing outreach/activism side and the original inward facing community.

If you want to join, either email EXMNA at community@exmna.org or contact the interfaithless team at community@faithtofaithless.com.
