I've done a little more research since seeing so many pro-Swainson's posters. I think my previous opinion of Hermit Thrush is wrong and based on regional bias, combined with a blind-spot in my birding skill. I am an easterner and we almost always see the "olive-backed" variety of the Swainson's Thrush. But you may have a "russet-backed" from Western N. America. They could easily become, or have been, 2 different species. Here are some photo links that illustrate that point.

This photo from Souix Falls looks alot like your bird. But, the spotting is lighter, more like I would expect of Swainson's. I think your bird has darker, bigger spotting. But, I can see this is very close to your bird.

This is the typical "olive-backed" we find in the east. It clearly looks nothing like your photo, rivaling vireos for the intensity of its "spectacles." The superloral and eye ring are extremely bold. There is no hint of red in the wing. The bill is noticeably thicker.

Here are some "russet-backed" in Colorado. They look much more like the bird you have with the same dark spotting and the narrow white eye ring. Some, according to Sibley (Western edition) are redder on the back and wing (your bird), some are browner, like these in Colorado.

Here is another obvious "olive-backed."
So, you probably have a "russet-backed" Swainson's Thrush.
Do let us know where the picture was taken. Canada is a big place to be from. It's amazing what variety exists inside many species between East and West N. America.
Happy to learn something today.
Thanks,
