This is a meaty report but it's pretty much the gold standard of what climate change mean's for Canada's environment:

The bottom line is that we don't know what's going to happen. We do know that it's most likely not going to be good.

Here's a snip:

Most watersheds in Canada are influenced by snow
accumulation and melt patterns. Maximum snow water
equivalent (SWE) is projected to decline in coastal British
Columbia, the Atlantic Provinces and the Great LakesSt.
Lawrence region, while increases are projected for the
Arctic coast of Nunavut (Brown and Mote, 2009).
For watersheds that contain glaciers, glacier retreat has
already been observed in British Columbia and Alberta
(Stahl et al., 2008; Marshall et al., 2011; Jost et al., 2012), and
this is projected to continue as the climate warms. As the ice
melts, this is expected to influence runoff, particularly during
summer. Marshall et al. (2011) assessed glacier runoff for
Chapter 2: An Overview of Canada’s Changing Climate 47
2000-2007 and future scenarios to 2100 (using SRES scenarios
B1 and A1B) for Rocky Mountain glaciers contributing to the
Bow, Red Deer, North Saskatchewan, Athabasca and Peace
Rivers. Projected changes in glacier volume range from -80%
(Athabasca) to -100% (Red Deer). Projected glacier runoff
changes between 2000 and 2050 for the A1B scenario are
-80% for North Saskatchewan River, -100% for Bow and Red
Deer Rivers, -75% for Peace River, and -60% for Athabasca
River. As glacier runoff contributed around 7% to summer
runoff in the Bow and North Saskatchewan Rivers in 2000-
2007, projected reductions need to be accounted for in
projections of streamflow during low flow periods in summer
and fall. Studies are also available for drainage basins with
glaciers in British Columbia (Bürger et al., 2011; Stahl et al.,
2008; Jost et al., 2012).
