Novice needing help with breaker/ furnace

[Mamamary]

New home owner here. I know zero about furnaces and breaker boxes. I need to shut off the power to my gas furnace but there is no switch located anywhere near the furnace (above, beside or on) and the breaker is not labeled. Would the furnace be the one with the biggest switch, on the far right on it’s own? Very much on my own here

not possible to determine which breaker through internet. i suggest you get a local qualified electrician who will have the right equipment to locate which breaker isolates the furnace, and perhaps fit you a form of local isolation. bear in mind, i'm in UK and don't know the regulations in Canada.

If it not labeled then shut off one by one untill you could hear no the more furuce working.and when found mark it up.

Hi,or bonjour?
If it is gas,it may only require a light electrical input,and be linked off another circuit.
Ensuring you have everything switched off,at the control switches,you could switch of each breaker,one at a time,at your fuse board,to find what powers the furnace (boiler?)

Is this a new home,or just new to you?

Mamamary if you have gas the no it’s not going to be the biggest breaker I would say it’s a 20 amp double pole breaker. After all you need power for is to run the fan and energize the gas solenoid and for the low voltage controls, it’s not going to draw that much current
