It's a Ranid from Ontario that appears to have no dorso-lateral folds, with makes it a Bullfrog, Rana catesbeiana, or a Mink Frog, Rana septentrionalis (Minks may have them or not, or something in between). The rear legs look to have dark bands instead of blotches, so this looks like a Bullfrog.

I'm not positive from your pictures about the folds, but they're pretty easy to see in person when you know what you're looking for. Compare the pictures at the top of first two links below. Green Frogs have the folds, one along each side of the back. Bullfrogs don't have them (Mink Frog included as the 3rd link to be complete)

The care of any of these species is the same, with bullfrogs needing even more space and being able to take down larger prey as adults.

Looks like Frejervarya limnocharis (rice field frog) to me. They are technically introduced in many countries as an exotic food item as well as for feeder purposes.

I've never heard of them being in Ontario or even Canada, and Amphibia Web's map puts them far away from here: BerkeleyMapper

Probably came in from Asian imports as what happened to snakeheads, catfishes and other asian food fish in the US

It looks like it has the lighter green bit over the upper lip between the eye and the nose- a definite characteristic of our natives (it can be blotchy in younger specimens) and not something that the Frejervarya limnocharis ​seems to share. Additionally, the skin texture appears uniformly knobbled like our natives and not like the intermittent ridges the rice field frog is described as having.

What characteristics of this frog make you think it's a Frejervarya limnocharis instead of one of our common Ontario Ranids that are consistent with the OP's photos? Evidence would have to be very compelling to favour a frog that I've never seen an account of in Ontario over one of our natives.
