Canadian Regulations In A Nutshell

Ultralights may be flown with an Ultralight Pilot Permit or with any Aeroplane category rating such as a Recreational Pilot Permit or a Private Pilot Licence.

New Challengers are most often registered as Advanced Ultralights.
Used Challengers can not be upgraded from Basic to Advanced.
Challengers imported from the US can not be registered Advanced.

Advanced Ultralights have all the privileges of certified aircraft such as Cessnas for daytime operations. Basic Ultralights are subject to a variety of operational restrictions particularly with regards to airports and airspace.

Both Advanced and Basic ultralights may be used by pilots to carry other pilots and by instructors to train students. Basic Ultralights can never carry non-pilot passengers no matter what licence is held by the pilot in command.

Only a Challenger registered as Advanced may carry non-pilot passengers, but only if the pilot in command holds a licence with passenger-carrying privileges. The Recreational and Private licences include passenger-carrying as does the Ultralight Pilot Permit with the Passenger Carrying Endorsement.

Ultralights obey the same rules of the air as other aeroplanes, including those concerning low flying. When not over built-up areas there is no minimum altitude but you must stay at least 500 feet, either horizontally or vertically, away from people or property on the surface.
