I can't tell that they are clearly Canadian, but I can tell they are not from the deep South, or New England, or New Jersey, or Brooklyn.
There's a vast "Middle America" in which the accent is not very distinct at all.
Then, in the middle of the country, the further north you go, the more the vowels in words like "out" or "house" change from an "ow" sound to an "oo" sound, and this fellow had just enough "oo" to make me think he was either from the northern part of the Midwest or Canadian.
