I think that's a hypothetical, and I can't really answer a hypothetical, especially when it involves suing someone.
In answer to the switch from paper to digital, I think it's important to note that both the Access Copyright licence and the Copibec licence covers a reproduction both in paper and digital. The fact that instead of producing paper course packs, they now just PDF it and upload it on a learning management system doesn't change the impact of consumption of works that are protected by copyright and not paid for. The mechanism to pay for it is in the collective licence, to make it simple and easy for professors across the country to make the reproductions they need to instruct their students, and ensuring at the same time that the payment flows back to the creators.
