Here is a couple of things I found in the CARs :
"specialty air services" - means aerial mapping, aerial surveying,
aerial photography, forest fire management, fire fighting, aerial advertising, glider towing, parachute jumping, aerial construction, heli-logging, aerial sightseeing, flight training, aerial inspection and surveillance and aerial spraying services;
623.65(b) and (c) Minimum Altitudes and Distances
(1) The following standards apply to the application for and the operation of an aircraft for the purpose of conducting aerial application, aerial inspection,
aerial photography or helicopter class B, C, or D external load operations at altitudes and distances less than those set out in CAR 602.14(2)(a) and CAR(16)(2).
Such an operation goes into part 702 Commercial Air Services
Canadian Aviation Regulations - Part VII, Subpart 2 - Aerial Work
By looking at the CARs I found nothing that would prohibit you from using any kind of aircraft for aerial photography as long as the PIC is a CPL and that the altitudes and distances used do not require a special flight permit.
So go ahead
