Looking for japanese mountain yam in canada

Hi everyone, this is my first post on permies so please excuse any mistakes as I have no idea what I am doing

I am looking for somewhere (in canada) to buy propagules/plants of Japanese mountain yam, a.k.a yamaimo or Dioscorea japonica. I found a post on this forum from a guy selling them, but the post is several years old and the account seems to be inactive.

Any help is greatly appreciated
