One of the BIG issues with FPV and Canadian Regulations is that our Model rules state that "The 'Pilot' MUST be in VISUAL CONTACT WITH THE AIRPLANE AT ALL TIMES" ... with FVP this does not really happen and so you are violating the rules as soon as you put the goggles on.
MAAC came up with a workable solution without going back to the law makers. All FPV must be done on a 'Buddy Box with a Trainer Cord' So the FPV Pilot is flying and the 'TRAINER' is in "VISUAL CONTACT WITH THE AIRPLANE AT ALL TIMES".
As to actual REGULATIONS... all that the Government KNOWS about is UAVs and these are primarily Military. So we (MAAC) are busy trying to dance around the situation before someone does something silly and CAUSES the Government to MAKE A LAW which is something that we really don't want...
Good Luck & Happy Landings!
