At 0:12 (to 0:13) in the McDonald's video she also sounds Canadian to my American ears. "We get asked that a lot." It's subtle, but both the "asked" and the "a lot" sound different than what I'm used to hearing. And, of course, the "out" at 0:17 and the "about" at 0:48 are a dead giveaway. Also, she uses the word "exact" several times starting at 1:35 and those sound different, too.
