> Moreover, this solution would involve secret non-consensual recording

In Canada at least, only one party has to consent to the recording

If you record your own phone calls that's not remotely illegal. Nor is it in my opinion unethical

Almost, as someone who used to work with telecom systems in Canada, while it is true that felony wiretapping requires 1 party to consent to not be illegal, it is not the only law. PIPEDA applies to only commercial endeavors, and requires two party consent.

This is why a company must inform you of the recording, but you do not have to inform them.

I didn't know that, thanks for clarifying

Still, as an individual wanting to record scam callers, you're in the clear to record calls that you are a part of

That's where I stand, also. You're a party to the conversation, it's not something that would implicitly be expected to be private (thus no bedroom recordings etc), it should be legal to record. I can see no justification for prohibiting it.
