Depends on where you are in Ontario. It's a pretty wide province. If you don't find anything by summer, you might consider looking at the Midwest Recumbent Rally in Wisconsin sponsored by the Hostel Shoppe. There are many manufacturers who bring bikes for test rides and there is a pretty good selection of used recumbents for sale. It is the first weekend in August this year:
