Quebec's public health department has confirmed a man from Montreal has died after contracting swine flu.
Health officials said Saturday the latest victim was already suffering from a separate illness. He was in his 40s.
Officials did not provide details about the other illness.
The Public Health Agency of Canada says just over five percent of the 3,515 people confirmed to have swine flu in the country have been treated in hospital, and estimates a quarter of those hospitalized had an underlying medical condition.
Five people across Canada have now died after contracting swine flu.
