Ontario has 25 species of reptiles. This is substantially more than any other province, as Québec (the second most diverse province) has ony 15 species. Many of Ontario's species are not found anywhere else in Canada. These species are generally limited to southwestern Ontario, the warmest part of the province. Ontario is the only province with more than one species of rattlesnake (although the Timber Rattlesnake has been extirpated from the province).
