I would have to say that under the circumstances of the Emergencies Act there wasn't a directive given to credit unions to notify when accounts were frozen.
I'd also like to clarify that if a credit union is suspicious about transactions, they don't freeze the account for that reason. They report it to FINTRAC. FINTRAC then takes whatever action it needs to with the RCMP, which would perhaps end up in a court order, and that's when a credit union would freeze an account.
The Emergencies Act overrode that, as you know, and made that court order unnecessary in these circumstances.
I can say that credit unions in a lot of cases—and again this is anecdotal, as I'd have to go back to get the information for you—did have conversations with their members on freezing their accounts. In fact, I saw a live-feed tweet in which someone whose account was frozen actually broadcasted the phone call from the credit union to announce that his account had been frozen, so he was notified.
It is at the discretion of the organization. I would say that credit unions have perhaps closer relationships with their members than some large financial institutions would have, and credit unions would have a conversation with their members.
