All non-restricted shotguns must have an overall length of at least . Semi-automatic shotguns must also have a barrel length of more than and have a capacity of 5 shells or less in the magazine to remain non-restricted. All other shotgun action types (pump/slide, break open, lever, bolt) do not have a magazine limit restriction or a minimum barrel length provided the overall length of the firearm remains more than and the barrel was produced by an approved manufacturer. Shotgun barrels may only be reduced in length to a minimum of . Non-restricted shotguns may be possessed with any Possession and Acquisition Licence (PAL) or Possession-Only License (POL) and may be transported throughout the country without special authorization and may be used for hunting certain species at certain times of the year. Semi-automatic shotguns with a barrel length of less than are considered restricted and any shotgun that has been altered so its barrel length is less than or if its overall length is less than is considered prohibited. Restricted and prohibited shotguns may be possessed with a PAL or POL that has been endorsed for restricted or prohibited grandfathered firearms. These shotguns require special Authorization to Transport (ATT). The Canadian Firearms Registry was a government-run registry of all legally owned firearms in Canada. The government provided amnesty from prosecution to shotgun and rifle owners if they fail to register non-restricted shotguns and rifles. The long gun portion of the registry was scrapped in 2011.

The round number restrictions apply only to the magazine, not the chamber, so it is legal to have a single-barreled semi-auto or pump-action shotgun that holds three rounds
