H1N1 has been blamed for the deaths of 10 people in Alberta, and health officials worry the flu strain might be making its way east and are encouraging people to get the flu shot.
In Saskatchewan, six people have now died after contracting influenza.
Quebec's public health director, Horace Arruda, said the H1N1 strain is the most widespread, and those who got the flu shot in 2009 -- when a pandemic of H1N1 killed about 300 people in the province due to complications -- are no longer protected.
