I love this Dollarama - considering the location, its huge and it carries quite a lot of different things. I was there tonight (and I go at least 2x a week) and to they're actually moving lots of things around so the whole store makes a bit more sense.
My favourite section is the containers section, where i've gotten quite a lot of variously sized plastic containers for my pantry and kitchen. The food section isn't bad either - if you can get past the fact that you're buying food at the dollar store, you'll start saving quite a bit of money on things like rice and snack food like candy and chips. It's usually busy but they have a huge seasonal selection and I rarely walk out without having purchased something. Love the fact that I spend $12-15 and walk out with a bag full of stuff!
