Canada is warming at twice the global rate according to a report by the Canadian Environment and Climate Change Department.
The report warns changes are already evident in many parts of the country and are likely to intensify.
Canada's Arctic has seen the deepest impact.
Its annual average temperature has increased by 1-point-7 degrees Celsius since 1948.
The report said the warming could be limited if global action is taken to reduce "carbon emissions to near zero early in the second half of the century.
