I use Tangerine (used to be ING) for all of my day to day banking needs and wouldn't hesitate to recommend them. No fees, app and website are pretty good. They offer investment products but I don't use those.
I still have a Scotiabank account but really only use it a couple times a month.
I'm with both Tangerine and TD... I'm about to move all my RSP accounts AWAY from Tangerine's investments because their online 'performance' summary is absolutely terrible. I chuckled when reading the OP first post about having to manually calculate the ROI at Scotia. LOL that's EXACTLY what you have to do for Tangerine! Scroll your mouse over a graph and record the overall portfolio balances and do the math yourself. It's no surprise Tangerine is owned by Scotia.
Their investment performance summary is a joke, it's like they don't want you to know how your investments are doing. They don't want you to be objective in your financial planning, they just want you to look at one graph that's sloping up, (with each deposit you make) and say, 'oohh that's pretty!' ...can you tell their user interface has actually offended me slightly? haha :)
In this day and age, it's unacceptable, too many competitors and too many options for customers.
So my advice for OP is to not go with Tangerine, as you'll find you have the same issue.
I'm going to move Tangerine RSPs to my Questrade account, and Tangerine will only be for my emergency fund within their high-interest savings account.
