Interesting question. May depend upon where you want to live & work for the decades following college.
McGill is well known in the US as is U of T, but I suspect that rescruiting may be skewed toward the Northeast US. Not sure how well UBC places in the US.
The safest bet is to attend UCal-Berkeley is you want to live & work in the US after college.
However, if you do not get into Haas (the business school at UC-Berkeley), but do get direct admission to business / commerce major at UBC or U of T, then Canada might be the wiser choice.
Of course, if you plan on earning an MBA, York & U of T are solid options that may (I don’t know for sure) be available to you at Canadian tuition rates–as opposed to paying the rate for an international student–which is the highest tuition rate charged by Canadian universities.
