If Trump forced Canada to abandon agricultural supply management, that would be a plus for Canadian consumers.

Ownership, management, and legal protections of data stored on the cloud are still in the wild west era. Unfortunately neither the US or Canadian government has been able to protect data from state sponsored hackers and criminal hackers. At some point I would expect legal challenges in both Canada & the US as these governments demonstrate that the cannot provide protection & privacy on the data that citizens are mandated to provide. The physical location and ownership of data is very much secondary in my opinion.
