Hello, Scenario1: If I get 2 admits, one from Canada and one from US.

So, for suppose if I applied my Canada visa and it's in processing, then later can I apply for US student visa before getting my Canada decision? And if I get both, is this scenario is right? Or we only need to apply either of the one? PS: Just got this doubt cuz if my US decision comes late and need to apply for Canada visa because it'll take around 2-3 months of time. Thanks in advance:))
