FWIW: I bank with TD Bank (in the USA - not Canada) - and I've got to say.... they are the easiest bank I've, personally, dealt with. I had a similar experience with both Chase Bank AND Bank of America - so I politely requested my account be closed at both institutions and I took my business elsewhere (in this case - Toronto Dominion Bank of North America).
If your bank is employing those sorts of practices - I'd just move elsewhere. I'm sure there is a bank in your area (can also look into Credit Unions) that will not hinder your ability to buy Bitcoin!
Best of luck with whatever course of action you choose.
Cheers!
