Costco Wholesale has opened its new warehouse location in Newmarket at 107 Harry Walker Parkway South, west of Highway 404 near Davis Drive. The store, which opened to members today, replaces the original Newmarket warehouse on Yonge Street that had served the community for nearly 23 years.
The former Yonge Street site is now closed as it undergoes conversion into the East Gwillimbury Costco Business Centre, set to open later this year. This development positions Newmarket as a significant hub for Costco’s operations in the region.
The relocation has resulted in the creation of approximately 70 new permanent jobs, in addition to retaining the 450 employees who worked at the original warehouse. This expansion underscores Costco’s investment in both Newmarket and the surrounding communities.
“With the relocation of our Newmarket warehouse, we can continue to serve all of our members in Newmarket and the surrounding area, and bring new consumers and businesses to uncover the benefits of a Costco membership,” said Gino Dorico, Senior Vice-President and Country Manager, Costco Wholesale Canada. “We are very proud to share this new, larger location with our valued existing and new members in the local community and throughout the area.”
Newmarket Mayor John Taylor echoed the sentiment, calling the opening a milestone for the town. “Many Newmarket residents have been excited about the new, highly anticipated, full-service Costco in Newmarket. The new warehouse has created hundreds of local jobs and valuable employment opportunities for Newmarket and the surrounding area. We welcome the investment in our community.”

Features of the New Location
At more than 166,000 square feet, the Newmarket warehouse is designed to offer members a spacious, modern shopping environment. Wide aisles and expanded services are at the core of the new facility.
The warehouse includes a large food court, bakery, rotisserie chicken section, and an expansive produce area. Specialty services include a hearing aid centre, optical centre, and a tire centre with five service bays. The location also introduces a fresh sushi bar, which is only the third of its kind in Canada.
A 24-pump gas station provides additional convenience, while over 1,300 shopping carts and more than 1,000 parking spaces ensure accessibility for members.
Like other Costco Wholesale warehouses, the new Newmarket location offers more than 3,200 items, including groceries, household products, apparel, and specialty goods. Members also have access to a wide range of services aimed at small and medium-sized businesses, including bulk supplies and products for resale.
The warehouse opening includes limited-time promotions such as $400 off an LG 86-inch 4K television and $35 off AAA whole beef tenderloin. Alcohol sales at the Newmarket location include beer, wine, champagne, and ready-to-drink beverages, aligning with offerings at Costco’s other Ontario stores.

Membership and Benefits
Costco Wholesale operates on a membership-only basis. A Gold Star Membership is available for $65 annually, while an Executive Membership costs $130 per year. Both membership types include a free household card and are valid at Costco locations worldwide.
Executive Membership provides additional benefits, including a 2% annual reward on qualifying purchases, exclusive merchandise offers, and access to special incentives on travel insurance, payment processing, and storage solutions.
Canadian membership remains robust, with over 17 million cardholders across the country. Members also have access to Costco.ca, where thousands of additional items are available, including same-day grocery delivery.

Costco’s Canadian Presence
Costco Wholesale currently operates 110 warehouses across Canada and 909 globally. The company has a longstanding presence in Ontario, with 41 locations across the province.
The first Canadian warehouse opened in Burnaby, British Columbia in 1985, followed by Quebec’s first location in Saint-Laurent in 1986. Today, Costco employs over 50,000 people in Canada, with more than 19,000 based in Ontario. The company’s Canadian head office is located in Ottawa.
