Gas stations thrive on one thing. Not gas, because I'll be flabbergasted if they don't have it.
They don't thrive on having a car wash (this one does) or bright lights (to reduce chances of you don't getting mugged), or tim hortons in their express stations (this one has one).
No, the key is location. Right off hurontario, when you are looking for gas, this location is an easy right turn. It has over 8 spots for filling and gets 3 stars for location and # of spots.
