What's the general principle behind choosing saving vs. paying off debt?
It has to do with return. I don't know if Canada has a matching feature on retirement accounts, but in the US many companies will match the first X% you put in. So for me, my first $5000 or so is matched 100%. I'll take that match over paying down any debt. Beyond that, of course it's a simple matter of rate of return. Why save in the bank at 2% when you owe at 10-18%?  One can make this as simple or convoluted as they like. My mortgage is a tax deduction so my 5% mortgage costs me 3.6%. I've continued to invest rather than pay the mortgage too early, as my retirement account is with pre-tax dollars. So $72 will put $100 in that account. Even in this last decade, bad as it was, I got more than 3.6% return.
