I would think the number of business bloggers out there who provide information to businesses about updates on Canadian sanctions is an indication that there isn't a go-to list that they can use. There's a lot of chat on the internet, “What about this? What about this update?”
For example, when we applied sanctions against Russia, almost every other day we were updating the list. This means that every other day a bank has to go through all of their accounts again. The same was true for businesses. We wanted to show that we were serious about Russia, but by doing it piecemeal we put a lot more burden on banks and individuals, so that it might have been better to get one list and release it. I appreciate that we wanted to show Russia how serious we were about its acts. However, the unintended consequence was that we put more burden on Canadian banks and businesses than we did on Russia.
