City, and only during the afternoon and early evening, although it has gradually expanded since its introduction. Similar programs exist in parts of Ontario; parts of Metro Vancouver and Vancouver Island; Alberta and Saskatchewan, where they are operated by each province's respective provincial health authority; Winnipeg, Manitoba; Saint John, New Brunswick; the Halifax Regional Municipality; Newfoundland and Labrador; and some First Nations. Many of these services operate part-time, restrict their clientele to certain demographics (such as youths), and have only a few teams to cover a large area. There are no mobile mental health crisis response teams in Quebec or Canada's territories, although the Nunavut RCMP began talks with the Nunavut Justice Department in 2020 to implement a unit. Following the death of Regis Korchinski-Paquet, the Toronto Police Service expanded its Mobile Crisis Intervention Team and began dispatching members of the team through 9-1-1 calls, rather than by back-up requests from other officers. The Toronto also launched a new crisis response team, the Community Crisis Service, in 2022. The service, which is composed entirely of unarmed, non-police specialists, operates 24 hours a day, six days a week. Prince Edward Island launched a similar program in 2021, where a specialized team of paramedics would attend mental health distress calls made to the province's mental health crisis hotline alongside police, who would be dispatched if necessary in their own vehicles and receive no specialized training.

Although the slogan was new and criticized as "divisive," these calls echoed earlier requests from Canadian police associations to offload some police duties, such as mental health crisis calls, to specialists. The adoption of tiered policing, which has both a similar means and a similar end to the "defund the police" movement, has been suggested as an alternative policy response to the expansion of police service mandates. Ranks Canadian police ranks are largely consistent with those used by British and Commonwealth police services. Uniquely, Canadian police services use the title "staff" in place of "chief" for certain ranks, such as staff sergeant or staff inspector. Chief of Police is the title of the head of most Canadian police forces, except in British Columbia (where police
