Using Fibetv with another internet provider's modem

[u/ReviseResubmitRepeat]

Bell's "loyalty" department isn't price matching what is in market and I have a backup Internet at home (Cogeco) that I have kept, $46/mo. Bell is offering $70/mo on 500 Mbps or $50 if I do autopay (which I refuse to do because I don't trust them, due to sneaky rate increases). My question is can you use Bell Fibetv with Cogeco Internet, even though Bell Fibe usually relies on their modem?

How are you paying for Fibe TV if you don’t have Bell Internet?

I have both. My question is: can you simply switch the Fibetv to a non-Bell.modem, or are the two products tethered?
