I believe that we should be able to see that from their overall corporate financial statements—the return on equity in the overall operation. However, to have it broken down according to the different divisions of it is a reasonable ask. They obviously don't want to share any more information with their competitors than they have to. If they're making a very strong return in one line of business, that's going to attract the attention of their competitors.
I understand why they don't want to release it, but again, my point would be that chartered banks are given a very special privilege: literally, the power to create money through new lending. In return for that, they should have special responsibilities to disclose to Canadians how that power is being used.
