>As far as I can tell accounts were frozen, not seized. Do you have a reference for donor accounts being seized?

When it comes to civil rights like Section 8 of the charter. There's no such thing as 'frozen'

They were searched, seized, and later returned.

You have to go back to figure out how the government knew what bank accounts to seize. They didnt go up to each person and ask to see their debit card. Police dont have a ready list of bank accounts to seize.

The source of the seizures was the gofundme leak by a hacker. Who has since been arrested, convicted, and is in prison for a separate hacking incident. Canada gave him immunity to his crimes during freedom protest. They took the donor list and seized from there.
