Well im goin to Toronto and Montreal from 24th march to 7th April and just wondering whether there was any shows on that might be worth visitin while i'm out there thanks Shakey.
If you're driving from Toronto to Montreal or vice-versa you can always stop in at Ottawa's Museum of Contemporary Photography. It always has something pretty amazing going on.
The McMichael Gallery, which is a bit outside of Toronto, has Yousuf Karsh exhibit on at the moment. There are also the Art Gallery of Ontario and the Musée des beaux-arts de Montréal located, respectively, in downtown Toronto and Montreal. These are large art galleries, and so probably have photography collection, though there may not be any particular photography-related special exhibit.
Drop by the Belgo, an industrial building converted into an artistic colony on 5 floors in downtown MTL. Also, have a look at galleries Dazibao and Vox, specializing in photography.
