Ontario has 24 species of amphibians -- more than any other province. This is
because Ontario extends farther south so it has species found nowhere else in
Canada, such as the Small-mouthed Salamander, found only on Pelee Island. Unlike
most provinces, not all species are found in the southern portion of Ontario.
For example, the Boreal Chorus Frog is only found in western Ontario. While 14
species can be found in the northern half of the province only 7 range as far as
James or Hudson Bay. Most of the species found in Ontario are also found in
Manitoba and Québec.
