Hi Nicky,
I wouldnt recomend you get one of these unless you have a large greenhouse, they grow big, and the most miniature forms grow to about 4 feet high, but they also have long and wide leaves, meaning a lot of room will be taken up
Also, I dont think any banana tree will survive in Canda year round, you can get hardy varieties but I think cold Canadian winters will be just too cold for them!!
