Ultramar is the eastern-Canada brand in Toronto’s mix — dominant in Quebec and the Atlantic provinces, with a smaller but steady GTA presence that, like Pioneer, now sits under the Parkland umbrella. Its Toronto-area stations are mostly neighbourhood sites rather than highway plazas, and they price in the value tier: generally under the national majors, trading closely with Pioneer and the independents on the same strips.
Because the network here is compact, the practical question isn’t "which Ultramar is cheapest" so much as whether the one near you beats its immediate neighbours today — which is what the live ranking below answers. Ultramar participates in Journie Rewards (shared with Pioneer), so linked CAA members take a further per-litre discount at the pump.
