Short answer for contractors: the city fee depends on the scope. Here are the flat fees we re-checked on Oct 29, 2026 against each city's published schedule.
For a change to a heating or ventilation system (the City's HVAC package for replacing electric, oil furnace, or boiler systems with a natural-gas forced-air furnace), the City lists a permit fee of $326.21 for its standard 10-day application service. That package also asks for heat-loss/gain calculations and a ventilation design summary.

On the 2026 permit fee schedule, stand-alone HVAC alterations and add-ons (unit heater, make-up air unit, exhaust fan, duct alterations, boiler/furnace replacement, and similar) are listed at $200.44 each. Stand-alone HVAC for occupancy groups A–F is also listed at $1.02 per m².

We did not re-verify a single flat "standard plumbing permit" fee for Brampton from that schedule today, so that figure is left out here.
Mississauga's 2026 Schedule B lists these residential mechanical flat fees:

City fees are what the homeowner or applicant pays the city. They are not your install price.
A second-unit or basement-finish building permit usually wraps structural, HVAC and plumbing work into one project. The homeowner already paid the city. Your quote is separate.
As of Oct 29, 2026 (America/Toronto), our filtered product leads show 73 Brampton second-unit and basement-finish permits in the Oct 21–27 window, and 16 Mississauga permits in the Sep 23–29 window. One count is one issued second-unit or basement-finish building permit kept after filtering — not every city permit.
