Residents of Newmarket are excitedly awaiting the arrival of the town’s first Costco.
Well, sort of.
The big box retailer has updated its website with an August 2025 opening for the long-awaited Newmarket location under construction at 107 Harry Walker Pkwy. S., though no exact date has been shared at this time.
The over 15,000 square-metre Costco currently wrapping up construction just west of Highway 404 is somehow both a first for Newmarket, while also managing to be nothing too new for locals.
While the Newmarket location will indeed be the first within the municipality’s borders, locals aren’t exactly starved of the wholesale giant.
Costco already operates a location at 18182 Yonge Street in East Gwillimbury, which is quite literally just a few steps north of Newmarket’s northern boundary.
So, while Newmarket’s first Costco from an official standpoint, the new location opening this summer will not be locals’ first taste of the brand’s big box savings.
But it won’t necessarily be an expansion, as Costco plans to transform its existing location north of Newmarket into a business centre once the Harry Walker Parkway location opens.
Costco has not shared details of a timeline for the conversion of the East Gwillinbury location, but it’s reasonable to expect that the opening of the Newmarket store will advance this process.
