A friend recommended Tangerine about 2 years ago, and I got on board because of the 50$ they give you when you start an account. So far its only been positive:
-50$ gift in my bank account, also I think 50$ to my friend who referred me
-No cost to have a checking account, unlike at my Caisse Desjardins account
-Index funds with lower costs than other banks (1%). All the operations where done online, very convenient.
So if we compare with Desjardins, I got 50$ the first year, and I didn't have to pay 50$ per year to keep my checking account. Therefore by switching I make more money, and keep more money. I definitely recommend this bank!
