Here is that amazing Art Gallery of Ontario (Aimia-AGO) photography prize. I think you have to be sponsored to enter. I like Liz Johnson Artur's work. $50000 CAD goes to the winner.

Every year, the Prize recognizes four artists working in
photography who have exhibited extraordinary potential over the last
five years. The artists are chosen via an international nomination
process. The AGO invites curators, critics and artists from around the
world to nominate two artists each for the long list. A jury of three,
led by an AGO curator, consider the long list to select the shortlist.
