It was very easy to go through RBC. All you have to do to get it is bring your letter of admission to prove you've been offered and you're intending on accepting. That's it. There's some other paperwork to make sure everything is legit, but once it's approved you don't need to do anything. RBC pays your tuition directly, so it's not like the money goes to you and you have to be reminded to pay it. As a Canadian, my RBC loan was 100% of tuition, so I had no worries.
Unfortunately the loan only covers tuition, no more. I had to get OSAP for other stuff.
