Fire stations and apparatus

Mississauga, Brampton, and Caledon underwent a region-wide renumbering of stations and apparatus in the 1990s. Each station is assigned a 3 digit number and each apparatus is given an alpha-numeric callsign corresponding with the station number. The alphabetic prefix identifies the type of apparatus, the first numerical digit identifies the municipality, and the remaining two numerical digits identify the station. The municipality identifiers are '1' for Mississauga, '2' for Brampton, and '3' for Caledon.

For example, Station 101 would be Mississauga's no. 1 station and P101 would be a pumper assigned to it, and so on. Spare apparatus (for Mississauga and Brampton) would be numbered with a 5 as the second numerical digit in the number (P150, S151, A152, etc.). In January 2020, as part of an apparatus redeployment plan, a second Pumper Company was organized and assigned to Station 101. Since the department had not previously run two Pumper Companies out of the same station, a numbering system for duplicate companies had not been utilized. To distinguish the second pumper from P101, it was given the callsign P131.

As of November 2023, MFES currently operates 21 active fire stations (with one under construction) and the following apparatus:
