As with all Restricted firearms (including all pistols, some shotguns, and some rifles) AR-15s are only allowed to be shot at certified firing ranges. In order to legally own and transport a Restricted firearm, a citizen must also register their firearm with the Royal Canadian Mounted Police and must apply for an Authorization to Transport (or ATT) permit from the RCMP Chief Firearms Officer (CFO) for their province. Additionally, the firearm must be unloaded, deactivated by a trigger or action lock, and be in a locked, opaque container during transport.[22]

Durability – ability to withstand abuse and long-term usage without mechanical failure or impaired performance
Ease of reholster – a rigid holster will allow a gun to be returned to it with one hand, while a flexible one may collapse after the gun is drawn, requiring the use of both hands to reholster.
Adjustability – a holster that provides for the adjustment of gun cant and position can aid in both comfort or concealment.
