Yes, registering pets in Calgary is mandatory. According to the Responsible Pet Ownership Bylaw, all cats and dogs over three months old must have a valid Calgary city license, regardless of whether they are domestic or stray animals. This requirement has been in effect since January 1, 2007, for cats and much earlier for dogs, making Calgary one of the pioneers of mandatory cat licensing in North America.

Legislative background and evolution of the licensing system

The pet licensing system in Calgary has evolved gradually over the past two decades. Mandatory dog licensing has been in place for over 20 years, while cat licensing was introduced in 2007 after a lengthy period of public consultation. Initially, the city authorities gave cat owners a one-year “grace period” to adapt to the new requirements, but full enforcement came into effect in 2008.

The updated Responsible Pet Ownership Ordinance came into force on January 1, 2022, and includes expanded provisions on controlling the number of animals in a household, expanded powers for the chief enforcement officer, and increased fines for violations.
