Be very afraid. This is a terrible idea. The next thing you know, you'll have U.S. agents (the worst agencies: a tie between ATF and DEA) kicking in doors and terrorizing folks in the dead of night. The unmanned drones, which I read somewhere are soon going to be allowed for use by even county and city PD'S in the States, will be flying over Canada.
The aforementioned surveillance drones could have a very nefarious purpose indeed. Some day as I drive happily homeward after indulging in the hobby, I'll be taken out with a sidewinder missile. All because I broke U.S. law whilst in Canada. Well, I was trying to be serious when I started, but you get my point.
