I understand your frustration Namworld, but I would like to point out a couple of things about credit unions in general and Interac e-transfers.

I do my banking at a CU. CUs always take less risks compared to banks, because they don't have owners who want to make a maximum profit like banks do. The owners of CUs are the member that have their accounts with them, and their main goal is to save money.

I think most CUs would have proceeded the same way Desjardins did in this case.

I wonder if there is a big police investigation against the buyer and police asked them to freeze you money during this time, but the are not allowed to tell you about it.

The problem here, as you mentioned, potentially is that the buyer used a hacked account to transfer the money.

Desjardings and CUs in general take fewer risks than banks do, because their deposits are 100% guaranteed, therefore their insurance goes up if they have too many fraudulent transactions that the insurance company has to cover.

I like Interac e-transfers because they are easy, fast and protect your privacy, buy the risk is that an account can have been hacked and now the hacker buys bitcoins to get the money out of the account. Another risk issue is that if the owner of the account is using e-transfers to buy illegal substances or other illegal activities and seller is linked to the buyer because of one or more legit transactions between the two.

I think using e-transfers with buyers that have a good reputation on localbitcoin is fairly safe.
