Thank you for the question.
I agree that the wording is quite similar. BQ-18, however, speaks to French language original programs, whereas PV-20 speaks to original programs to be broadcast in both official languages.
I will also ask about BQ-24, which I believe passed on the first day of study and also had a similar element, but I'm a bit confused about the process there. There may be some connections to be made to BQ-24, as well.
