Yea I don’t think “any bank” will give you 4%. Just checked CIBC and there are a number of conditions and also the bonus interest only applies for the first 4 months on your first account: https://www.cibc.com/en/special-offers/smart-savings-bonus-i...
I made a mistake, I equated Savings Account with a GIC (which is like a cashable certificate of deposit). In Canada they can both be referred to as a TFSA, or Tax-Free Savings Account.
However the GIC is not like a savings account where there are minimum balance requirements to get an advertised rate.
TD is not even close to offering 4% https://www.td.com/ca/en/personal-banking/products/bank-acco...
And RBC only gives higher interest rates for 3 months https://www.rbcroyalbank.com/investments/psi/hisa.html
