This is per Ducks Unlimitied at http://www.ducks.org/
"According to 2011 U.S. Fish and Wildlife Service and Canadian Wildlife Service waterfowl surveys, total duck breeding population estimates have increased in most traditional survey areas in Canada. The only exceptions are in northern parts of the British Columbia/Western Boreal Forest Region, which could be a result of birds short-stopping to take advantage of the excellent habitat conditions in the Prairie Region. Prairie breeding populations have increased by 41 to 66 percent since last year and by 2-43 percent compared to the long-term average. Breeding habitat is favourable in most of the Eastern Region, and Ontario is expecting an above-average production year.?
