What kind of Frog do I have?

[GrifTheGreat]

Hi All; I got this tadpole in a shipment of comets at work. I took him home and did some research and to my surprise he has morphed very quickly. Can anyone tell me what kind of Bull Frog this is? I'm guessing American Bull Frog. If I'm correct, are they native to Canada or should I keep him?

I'm not entirely certain that its an American Bull Frog, but does looks very similar. post the picture in the Frogs section of the forum for true frogs. You may received an exact species from that are. Looks to be healthy though.
