I think interac e-transfer has a $3000CAD per transfer per day limit. Of course, if you keep having 3k etransfers going into your account everyday, that might raise an eyebrow. There is no minimum or maximum amount of etransfer that you receive that will get you “caught”, or for a more realistic term, get you “noticed” by the bank. How to get noticed is all very nuanced. It’s really up to the bank, or more probably, the bank’s monitoring algorithms to flag you or not. It might be due to receiving large amounts over a short period of time. It might be due to receiving a single small amount etransfer from a suspicious account. Or any other reasons that you can think of or that you don’t know about. Just keep in mind that everything that goes through the fiat banking system is recorded and can be traced back to you in real life. That is the risk you take when receiving etransfer from strangers online.

My assumption is that you don’t want CRA to find out or tax your bitcoin “capital gains”. If you ever get audited, CRA usually checks for records and books from the past 6 years, but if they suspect fraud, they can go as far back as they want.

If you want to convert bitcoin to fiat kyc free, tax free, it might be easier to go the gift card or prepaid Visa card route. But it’s easier to run into scams doing p2p gift cards, so personally, I would stick to companies like bullbitcoin or bitrefill for those.

So, always think adversarially and make decisions based on your risk tolerance. The last thing you want is to get noticed by the banks and have them report you to the CRA.
