Not to worry! You're in pretty good shape financially (and congratulations on burying your student loans, that's a big win).
My approach for investing as a kind of lazy Canadian has been to put as much as I can in my RRSP and TFSA, invest it all in VGRO and hope it works out. This works pretty well for me because I have a lot of life stability and somewhat more income - I mostly use Questrade to do so.
I kind of get from the tone of your question that you might be more risk averse than I am (and that's probably sensible, I'm not strictly normal). So with that in mind, right now in Canada you can get ~ 5% interest on a GIC, which is basically a certain return. That's much better than what you're doing with your RRSP Savings Account right now (and it's also available through Tangerine, which might make things easier). It's relatively hard to access your RRSPs anyways, so I don't think you're losing anything in terms of flexibility.
A savings account with $3000 CAD is probably reasonable as an emergency fund, making 1% on that feels pretty good to me.
For the RBC account - A $14,000 loss in your TFSA hurts, for sure. I don't have much to say that can take away that sting, but it's a lesson that I learned too (trying to be clever with Canadian oil and gas stocks - it turns out I am less clever than I thought). On the other hand, you still have $2000, and you could put that into a balanced index fund ETF (there's a lot of choices - all you really care about is that the expenses are pretty low and that the risk feels okay - I use VGRO but lots of others on the forums have different ideas). The advantage of doing that with this amount of money is it'll give you a chance to build up some trust and feel a bit better about the fact that one bad choice doesn't make you a bad investor.
In the future, there's considerations like the fact that the Tangerine EFT portfolio has somewhat high expenses ... but I think your first priority should be figuring out how to get more of a return on that $52,200 in your RRSP.
(also, congratulations on the house - that's an enormous windfall if you ever decide to leave the area)
