I have no experience with Canadian undergraduate business education, which is what the author of the article appears to be taking, but I don't doubt that it's less challenging than engineering. Canadian engineering programs have higher entrance standards than this, and are accredited by a national authority for engineering education. And we still had to work fairly hard, especially in the fundamental Computer Engineering courses, even though they are less challenging than courses at MIT.

However, Canadian schools are also not generally the elite institutions that the Ivy League+MIT+Stanford are either. The top Canadian universities are public institutions with larger undergraduate populations that to a reasonable extent serve regional demand and need, rather than attracting the best from across the land (with some exceptions). A more reasonable comparison might be agaisnt some of the top 10 to top 30 public schools in the US, instead of MIT or Cornell or Oxford.
