Licensing and permits in Ontario

Licence required. Technical Standards & Safety Authority (TSSA); Skilled Trades Ontario for non-gas refrigeration/AC work. For any gas furnace or gas appliance work, confirm the technician holds a valid TSSA Gas Technician (G2/G1) or Domestic Appliance (DA) certificate.

Residential building permits in Ontario are issued by the local municipality's building department under the Ontario Building Code (not by the province directly), so exact triggers vary somewhat city to city. In London, permits come from the City of London Building Division.

Tax: HST applies to labor on home repair and improvement services in Ontario — unlike some US states, there's no separate labor exemption, so a contractor charges 13% HST on both materials and labor for taxable home-service work.

Best time to book in London

Book non-urgent tune-ups and replacements in spring (Mar-May) or fall (Sep-Oct) — shoulder-season scheduling avoids the summer AC and winter furnace demand spikes that push both price and wait times up. Peak demand: June, July, August, December, January and February. Typical job length: 1-3 hours for a repair visit; 1-2 days for a full furnace, AC, or heat pump installation.

DIY or pro? Homeowners can safely handle basic maintenance like filter changes, clearing debris around outdoor units, and thermostat swaps; anything involving refrigerant, gas lines, or electrical hookups requires a licensed HVAC technician.
