As mentioned by @Cawtau, right now we’re focused on offering Fido Internet in Ottawa and parts of Southern Ontario and the service is delivered through the Rogers cable network already established in those areas.
Should we decide to expand our network in the future, we'll keep everyone posted on Fido.ca.
Welcome to the community!
Since Fido is a subsidiary of Rogers, they would use Rogers' cable infrastructure. While there are apparently some select areas of Eastern Quebec where Rogers cable is available (see here), it is not available in the rest of Quebec. I think it's rather unlikely that Fido would provide home internet outside of Rogers' territory.
You should note that while Fido Home Internet is available in some other Provinces, it is only available in Rogers operated territories of those Provinces (see here).
Hope this helps
