No. Companies already know how much they spend on disclosures, and there's a whole audit industry built up around financial audit. It's going to depend significantly on the type of company.
One of the requirements is.... Someone mentioned that SMEs are an important part of the Canadian economy. You typically have to think about that. If you have initial legislation, you probably don't go for the SMEs to start with. You go with large companies that are more capable of doing this work, but large companies source much of their product from small companies over time. If they are expected to do scope 3 disclosures, which is essentially carbon in the value chain, eventually they need to source that information including from SMEs.
It is a whole-of-economy approach, but disclosures are something that the whole economy already does. This is adding in one more objective.
