Canada has no registration requirements for drones under 2 Kilograms (4.4 pounds) that are used for recreation. You don't have to be a Canadian citizen to fly a Phantom in Canada.
BUT...
As gosports1 points out, we have some of the most draconian rules when it comes to flying drones in this class. The list is here:
Exemption from Paragraph 571.08(1)(b) of the Canadian Aviation Regulations - Transport Canada
Some of the rules, I'm pretty sure most Canadians aren't even aware of and probably break on a regular basis.
- Absolutely no FPV of any sort.
- Maximum altitude 300 feet
- No flying within 5 nautical miles of any built up area. 'Built up area' includes cities, towns and hamlets. (Canadians living in a town or city cannot fly in their back yards or in local parks or other open areas).
- You have to carry a printed copy of the federal rules (shown in the link above) when flying
- You have to have a $100,000 public liability insurance policy for the drone and you must carry it with you when flying.
- You must carry a printed copy of the drone's limitations (ie, service ceiling, maximum flight time, maximum range, maximum/minimum operating temperatures etc).
- You must produce these documents on the request of a police officer or Transport Canada inspector.
