Went to the Falls this weekend. I saw places that had makeshift signs for the prices in the GTA. It was pretty insane. When we got to the Falls, there was a full serve pump that had 95.6 so I filled up before I left.
There is a gas station on North Service Rd in Mississauga (west of Cawthra), Pioneer I think, full serve...cheaper than self serve everytime I have seen so far. Filled up at 90.2/L while self serve was at 94.1
