This award would go to Tim Hortons Coffee Shops. "Timmy" restaurants and drive-throughs are located in practically every town and city across Canada(even in the U.S.).
You'll also find Tim Hortons service areas in gas bars and company cafeterias. We have one where I work in the Mississauga postal plant.
When we bought our house in Brampton, a Tim Hortons shop was located in an Esso station close by. It's only a ten minute walk from our home.
My coffee fix consists of two "Timmys" a day.
I must add, however, that "Country Style Donuts" has better donuts and muffins than Tim Hortons.
The original Tim Horton was a Toronto Maple Leaf hockey player. He died in a car crash in 1971.
