Canada
The chief executives of boroughs (arrondissements) in Quebec are termed mayors (maires/mairesses in French). A borough mayor simultaneously serves as head of the borough council and as a regular councillor on the main city council. The scheduling of municipal elections in Canada varies by jurisdiction, as each province and territory has its own laws regarding municipal governance.
As is the practice in most Commonwealth countries, in Canada a mayor is addressed as His/Her Worship while holding office.
In a few municipalities and townships in Ontario, the reeve is the elected head of the municipality, and the second-in-command is referred to as the deputy reeve. Historically, in some small townships, the title reeve was used instead of mayor. In some other municipalities, mayor and reeve were two separate offices, with the mayor retaining leadership powers while the reeve was equivalent to what other municipalities called an at-large councillor. Today most municipalities in the province now designate their elected municipal government heads as mayors, but a small handful retain the position. This continues to be the case in the following municipalities and townships:
Howick Township, Huron County
North Huron Township, Huron County
Beckwith Township, Lanark County
Drummond/North Elmsley Township, Lanark County
Lanark Highlands, Lanark County
Montague Township, Lanark County
Tay Valley Township, Lanark County
Township of The Archipelago, Parry Sound District
Alberton Township, Rainy River District
Chapple Township, Rainy River District

The reeve is also the chief elected official in most of Alberta's municipal districts.
The elected heads of rural municipalities (RM) in the provinces of Manitoba and Saskatchewan are usually referred to as a reeve.
