In a report released today, the Council of Canadian Academies narrows down the threats posed by climate change into the most pressing dozen.
Right at the very top is infrastructure, with extreme weather posing a threat to buildings from homes to power grids.
For coastal communities, climate change is slowly raising sea levels, making floods more common and surges heavier and more powerful.
Northerners are not only faced with permafrost melting away from under their homes and shorelines, but also with increasing danger from travel on land and sea ice.
The report's co-author, John Leggat, says ways exist to mitigate those problems, if Canadians can be convinced to pay up for them.
He points to a recent poll that suggests there is little willingness to pay for climate change-related problems.
