As far as standardization, there is obviously a wide range of policies across Canada. At Dalhousie University, the researchers own their own intellectual property. That can be altered by contract, if they choose to contract with a company that wishes to deal directly with the university versus the researchers themselves.
That being said, that's defined in a collective agreement. If you were looking to standardize the IP policies across Canada, it's possible—it has been done in the U.S.—but it would mean changing every collective agreement.
