It may seem hard to believe now, but dry, frigid Ellesmere Island in Canada’s high North was once teeming with alligators, turtles and rhino-like mammals. It turns out that the now-glacier-covered island in Nunavut was actually a pretty temperate place back in the early Eocene period, 52 or 53 million years ago.

There is a population north of Toronto, as well as one south but the two populations are distinct and do not extend into the city. While T.O. has it’s share of lounge lizards, the only ones I’ve ever seen inside a house, were in a cage, and cost a bundle at the pet store.

Canada has five native species of lizards, and the introduced Common Wall lizard in British Columbia. Two species are found in the arid prairies, one skink lives in southern Ontario, and two species live in southern British Columbia. These amazing lizards have a unique defence of squirting blood from their eyes.

Whilst 23 species of crocodile exist in the world, none of these are native to Canada. No, these reptiles seem to prefer constantly warmer climates of the southern regions of America and further afield.

Mosquitoes With mosquitoes carrying diseases like West Nile mosquitoes are one of the deadliest insects in Canada. Most people infected with the virus have no symptoms or they have flu-like symptoms.

Not likely. An alligator possibly could for a short while, but the water temperatures (even during the summer) are far too cold for a crocodile to survive. , Reptile keeper and breeder, wildlife observation and ecology hobbyist.

Canada is too far north for crocodiles and much too cold for them to survive. In general crocodiles live in the more Southern areas of the world than alligators. Alligators don’t exactly live in the north, but they are a bit more adaptable to cooler temperatures.

There are 23 species of crocodiles, none of which are native to Canada, he said. The zoo has about six, which the crocodile will join if captured.

Alligators. Despite their manifest ability to kill prey similar to or larger than humans in size and their commonness in an area of dense human settlement (the southeastern United States, especially Florida), American alligators rarely prey upon humans.

It’s very rare for an alligator to chase a human on dry land. And the average human could easily outrun an alligator, zigzagging or not — it tops out at a speed of around 11 miles per hour (18 kph), and it can’t maintain that speed for very long [source: San Diego Zoo].
