Toronto-based photographer Edward Burtynsky and co-director Jennifer Baichwal won $100,000 for their documentary Watermark last night from the Toronto Film Critics Association. The Rogers Best Canadian Film Award was much deserved by the stunning film, co-directed by the pair behind Manufactured Landscapes (which also won them the TFCA's Best Documentary Award in 2006).

Watermark journeys to 10 countries to trace the way water shapes our world - and the way humanity shapes water. Like Manufactured Landscapes, it's a must-see, even if your inner environmentalist is about the size of a baby squirrel. The Best Canadian Film prize is the biggest payday of the annual Canadian arts prizes, which one can only hope will be invested in more stunning work from the local photographer / filmmaker duo.

Other winners included Joshua Oppenheimer for the doc The Act of Killing, which took home the $5,000 BMO Allan King Documentary Award. Ryerson students Walter Woodman and Patrick Cederberg also received $5,000 for their short Noah, while Norman Jewison used the $50,000 Technicolor Clyde Gilmour Award to fund Quebec filmmaker Jeff Barnaby.
