Canada

legally speaking they can do it. I'm pretty sure all of the big 5 banks in Canada have that clause. They can also freeze your bank account for any reason at all, they don't have to prove anything. If they suspect anything they can unilaterally close your account too. It's all in the agreement.

I'll be going on Tuesday to open up a new account at the local credit union and you can bet I'll be reading that part of their agreement. I'll let you know if they apply that clause as well. If you bank in Canada you really should check - think about it, anyone could forge your signature on a loan, default and then they can take money from your account with no proof that you signed the documents. Scary shit. I asked them to prove that I owed the money (because I'm not sure which loans I signed for and which ones my ex may have forged - his business partner said he's forged a lot - so I want proof) and they didn't - they just took the money.
