Trying to Find Riccia fluitans and Glossostigma in Canada

i've never seen either of those in the Toronto area either. I'd like to get rid of my Sagittaria from the foreground and replace it with Glosso, but I don't want to order online. Do you guys have an aquarium society around there? I just found one here in Waterloo where I live during university, and I might check it out if I ever have time, see what they're up to.

I've never ordered from them, but I've heard a few good reviews.

edit: I just checked. They have riccia but not glossostigma
