American "A" vs. Canadian "A"

I’m a rising Canadian senior applying to the States. For us, in Ontario at least, an A is 80-100, a B is 70-79 and so on. I only have one Canadian “B” on my transcript, but my question is, when applying to the States will universities consider an 85 on my transcript as an A (due to Canadian grading standards that apply to my school) or a B?
