No vaccinations are necessary for travel to Canada. The West
Nile virus, spread by mosquitoes breeding in stagnant water, poses
a threat during summer months in rural areas, so insect-repellent
measures are advised for those visiting the countryside
particularly in Saskatchewan, Alberta, Ontario, Manitoba, and
Quebec. Rabies is a problem and can be spread by a bite from small
animals such as racoons and bats. Medical care is excellent, but
expensive, so medical insurance is advised.
