it is legal in Montreal at a church called "Céu do Montréal" as it is considered a religious practice. 5 interesting points
1 They prefer to remain low profile to avoid legal harassment so they have not been in the news
2 They claim to be Christian and believe in Christ and the prophets and the Angels
3 Jeffrey Bronfman, of the rich and philanthropical Bronfman family (Seagrams whiskey) tripped on it in Brazil and has since used his influence and $ to legalize religious use in the USA and now just arrived in Canada
4 rainforest ceremonies have become very expensive and commercial. I would be very careful in trusting a jungle retreat because of these reasons.
5 you can make it yourself by ordering it on the net from places where it is legal, but if caught you go to prison and it seems like a very bad idea to be your own Shaman using drugs with bad quality control
