Hmm, c.i., Toronto is close to Niagara, not a bad drive or you could take a train. My suggestion would be to go there for a tour. I can certainly get you a list, but if you want some wines that are uniquely Canadian, you may want to try Henry of Pelham's Baco Noir, a native hybrid grape, and another hybrid, Marechal Foch, which Inniskillin makes very well, especially the 'Old Vines' Foch. These reds are quite different from your average Cab, Merlot, Pinot varietals...a little foxy, a bit 'wild', with gobs of fruit and a backbone as well. Perfect for drinking now. Penninsula Ridge and Malivoire are two other up and coming Niagara wineries. Seeing as you will be here in the summer, the Malivoire 'Ladybug' Rose competes very well with the great dry roses of Tavel...sort of a dinner rose, but perfect for just sipping outside as well.
