internet with fibre ?

I don't think they have access to a fibe network.

Fizz is using Videotron network.Most of it it's fibre but the cable that goes into the houses is still coaxial.

It is largely a coaxial network.

Same as videotron

Fizz uses the same network as Vidéotron. There is fibre to the node but not to the house. Fizz network peed and reliability is comparable to Vidéotron.
