The convenience store is clean and bright with plenty of things for you to pick up if needed be. But I would have to disagree with the assessment of the previous reviewer's perception of the guy at the counter.
Last I was in the store I was simply picking up some snacks, immediately afterwards I witnessed a bizarre incident:
Basically two guys behind me wanted to buy a lighter for their smokes and the price for them was something like $1, (so it would come up to like $1.13). So when the customer was about to pay for it, he casually asked why it was $1.13 and not $1. The response from the cashier was "Are you stupid?"
The baffled customer responded "What?"; which the cashier replied" Are you stupid? Ontario has taxes of 13%. Don't you know anything?" Shortly afterwards, the customer and the cashier had quick remarks towards each other.
I was on my way out when this happened but I found the response from the cashier quite rude even though it was not directed at me. Upon reflecting on the event I can safely say that those customers didn't say or do anything to instigate this kind of situation. So I suppose everyone has good or bad days, but in my opinion the cashier guy inconsistently treats his customers positively.
