Municipal Service Offices
Who we are
There are 444 municipalities in Ontario. Each Municipal Services Office (MSO) provides services and advice to municipalities and the general public located within their specific geographic areas.
There are five MSOs of the Ministry of Municipal Affairs and Housing located in Kingston, London, Sudbury, Thunder Bay and Toronto.
Who we are
MSOs serve as the ministry’s liaison with the municipal sector. Staff come from a number of professional backgrounds, including land use planning, housing, municipal administration and municipal finance. In addition to this experience, staff have the ability to reach ministry experts in most areas of municipal activities when further information is required.
