Certainly, interfering with legitimate hunting activities is not permitted under the law. I know that in the province of Ontario it is not permitted under law right now. Cam may have more insight into that than I have.
I'm not personally aware of any drone activity interfering with hunting. That's not to say it's not coming. If you can land a drone on the White House lawn, perhaps this is something we need to be concerned about, but I'm not personally aware of any examples of its happening.
