In what scenario for a stove would using a 50a breaker for #8awg be permitted?

FWIW in Canada 8/3 has been allowed for some time on 50 amp range circuits.

FWIW in the US

Note 4 to Table 220.55 would allow you to power a Household range up to 13kw on a 40 amp circuit.

Correct, however the CEC has no 60*C restrictions for NM like the US.

Probably because 75% of the NM in Canada is operating below freezing (joke)

No joke :lol: Believe it or not you may not be far off... In Canada Id imagine the probability of NM winding up in a hot attic is less probable.

Was this in the code?

No, it was not in the code, just some guys noticed the new spec for NM-B and thought that meant they could treat it the same as other 90 degree conductors.

Makes sense.
