The evergreen's an Eastern hemlock... and late fall/winter is the time to prune. The maple has leaves way too big for bonsai, not practical to try and reduce them (is it a Norway or sugar maple?) and I'd put it back in the ground. Where are you in Canada (I'm here too, in a similar zone)? There may be a good bonsai club near you that could help more with the hemlock.

Thank you for the ID!

I'm fairly certain it is an Amur maple. I'll leave it in the pot for kicks. I've got a full size tree in the yard and the seeds sprout up all around the tree every summer, so no need to put it back, really!

I'm in eastern Ontario. I'll see if there is club in the area, didn't even think of that :)

Thanks again

Ok - one thing though, maple roots grow laterally and shallow, so you'd be much better off to put it in a much wider, if not particularly deep pot, and use lots of grit in the mix for quick drainage. I'm not sure what the brown spots are about (from here), but wait and see if you find insects, or what looks like overwater damage (it's better to water less often, though do it fully when you do it).
