Tularemia, also known as rabbit fever, is a plague-like illness that was first documented in Tulare, California in 1911. We know little about tularemia in Canada except that it appears to be rare in this country. The first known Canadian case was recorded in Timmins, Ontario in 1930, and the disease is considered to be endemic in Central and Western Canada, less so in the east.

Little is known about squirrel ticks but, as their name suggests, they feed primarily on tree squirrels and, to a lesser extent, on snowshoe hares. They also feed on animals that prey on squirrels. The many records from the Maritimes through to Ontario suggest these ticks are well established in much of Eastern Canada.

The winter or moose tick (Dermacentor albipictus) is a large reddish-brown to grey-brown tick that's similar in appearance to other dermacentor tick species (American dog ticks, Rocky Mountain wood ticks) found in Canada and inhabits an extensive geographic area that includes every Canadian province and territory. The farthest north they've been found is southern Yukon.

The Asian longhorned tick (Haemaphysalis longicornis) is not native to Canada but it has started to cause concerns in this country.

Once confined to Australia, China, Japan, Korea, New Zealand, Russia and several Pacific islands, Asian longhorned ticks were detected for the first time in the wilds of New Jersey in 2017 after occasionally turning up on imported animals at American seaports. Thanks to some entomological detective work, we now know that Asian longhorned ticks have been making their home in New Jersey since as far back as 2013. And they’re spreading fast. Between 2013 and 2023, breeding populations went from non-existent to spanning at least 19 US states.
