Unidentified Fossilized Tooth Found Today In South-Central Great Lakes Region (Canada)

[Great Lakes]

I found this fossilized tooth today submerged within the Nottawasaga River (North of Toronto, Ontario, Canada - within the Great Lakes Basin).

Can anyone help me to identify it? I've included some scans below. Thanks in advance.

NOTE: The findspot is within the vicinity of this location:

I'll try some better macro close-up images later, as these scans are not well lit enough to see the detail.

A sharp, well lit image of the chewing surface (and good measurements) would give us the best shot at identifying it.

Thanks. I will try my best to upload a better quality scan showing the chewing surface shortly.

Unfortunately the camera focused in on the 10 cent piece instead. Yes better lighting and multiple shots of different angles.j

This is a white-tailed deer (Odocoileus virginianus) fossil molar next to a US quarter. If your chewing surface looks the same, we have a match.

Looks like it is an upper M1 or M2 of a deer.

Thanks very much for the helpful replies.
