I tend to agree with @[email protected] that we have likely not reached a critical mass where this community is active enough that people feel the need to use more niche Canada-adjacent communities. That said, my strategy has been to pepper the more niche communities with content in the same way as the main Canadian community so that when people do feel the need to look for them, there is something there for them to glom on to and participate with.

It seems to be working. All the more niche subs I take an interest in are growing and have some level of interaction. Not quite enough to snowball into self generating content quite yet, but as this sub grows, so too will those.
