One of the challenges with transparency is that copyright is part and parcel of the contractual relationship between creators and record or production companies, as governed by the Act respecting contracting by public bodies. Confidentiality issues make it hard for legislators to require a certain degree of transparency, though it can be done.
The transparency issue was raised many times during the reform to the Copyright Board of Canada. It's a way of making sure that creators appearing before the board know, at the very least, the basis on which decisions are made. There are probably better practices elsewhere in the world, but, there is a caveat: Solutions that work elsewhere won't necessarily work in Canada.
I think that transparency, especially for digital platform companies, is already at the forefront of Minister Joly's program. You've heard it many times in the Creative Canada program. The notion of accountability for digital platform companies is included as well. These companies clearly understand that there is a copyright dimension to the support they have to provide to creators.
The declaration signed between Canada and the French government in April specifically mentions a shared responsibility between governments, digital platforms and civil society to value copyright and transparency, specifically the transparency of algorithm models.
