You might check on the Lily Auction. I do not know if Mary Jane still sells on there or not. She used the seller name Bubbles. If you have any plants to offer in a trade you might consider posting on the TRADE Forum here on ATP.
One thing I will mention is that I do not know how well Mary Jane's plant would do in Canada. I have had to give up several of hers that I bought because they did not like it here in Indiana. The plants grew well for the most part just did not seem to want to bloom for me.
