How much does a furnace replacement cost in Canada?

Reliance Home Comfort's 2026 Canadian pricing: single-stage $4,500–$6,000 installed, two-stage $6,000–$8,000, modulating $8,400 and up. The tier explains most of the spread between quotes.

Most Ontario homeowners land between $4,500 and $6,500 installed for a standard swap, and Ontario sits at the top of the national bands. Prices are usually quoted before 13% HST.

For a straight swap the quote usually covers removal, the unit, venting, and commissioning. Paste your own low quote here, or keep the tier default above.

Two quotes $2,000 apart usually differ in the middle line items, not the box. Get the breakdown in writing and compare line by line.

HomeStars puts a standalone AC install at $3,000–$7,500; doing it with the furnace usually saves hundreds to about $1,500 in labour overlap. A furnace-plus-AC pair typically runs $7,500–$12,000. Leave blank if the furnace is all.

A home heated by baseboards that needs full ductwork can run $7,000–$12,000 or more in Ontario; national ranges run $5,000–$15,000. Always price this as its own line.

Enbridge installs the first 20 metres from the property line free; beyond that the current Rate Handbook charge is $170.06 per metre, invoiced on the first gas bill. Set 0 if the service already exists.

Calgary installers commonly show the permit and inspection as its own line at $180–$320. A modern condensing furnace usually needs one, because the venting changes. Let the installer pull it either way.

Outside the metros, equipment delivery and a thinner contractor bench can add $500 to $1,500 over a city price. Leave at 0 in the city.
