I seem to recall there being service levels at banks in Canada and maximum numbers of transactions per month until one gets hit with per-transaction fees. I was told explicitly when I opened my TD Canada Trust account there that it was imperative that I both keep money in the accounts and use them occasionally or dormancy fees would accrue (and if there was no money left, they'd then slam it with overdraft fees).

The benefit of US banking despite lax regulation was that there's a ton of different banks and credit unions to choose from. Some are great and some are shit. Literally hundreds to pick from. Canada there was like 5 big banks, a large credit union, and then depending on your area there was maybe perhaps a small community credit union.
