C$0.03 a litre between Ottawa-Gatineau and Thunder Bay

On a 55-litre tank that is C$1.70; filling weekly for a year, about C$88.66. Within a single province the gap is mostly local taxes and transport distance from the nearest terminal — provincial fuel tax applies equally across Ontario, so it is not the explanation here the way it is between provinces.
