Newmarket is the retail hub of northern York Region, and its stations follow the retail: Yonge Street and Davis Drive carry the historic clusters, while the Green Lane and Leslie Street corridors near the 404 serve the newer growth. Prices typically sit a cent or two above the Vaughan-anchored lows further south — the discount pressure thins out north of Highway 407 — but competition along Yonge keeps the market honest.
For 404 commuters the calculus is familiar: the interchange stations price for highway traffic, and a fill timed to the southern end of the commute — Richmond Hill or Vaughan — often beats the local pump. The list below ranks every Newmarket station we track by current price, refreshed hourly, with the Aurora page next door for the Yonge Street comparison.
