I'm not sure how many stations in the GTA offer the V-max Diesel, but we have 2 grades of diesel. There is the regular ultra low sulphur diesel and then the performance ultra low sulphur diesel which is formulated for higher revving diesel motors.
In Saskatoon there are only 3 shell stations that carry this formulation and I do notice a difference, especially in the winter.
If you go online to the shell site you can get a list of stations that carry the V-max if you are interested. I always have the addresses of these stations whenever travelling so to keep the good stuff in the car.
