Shoppers and business owners in Mississauga, Brampton, and Milton are getting ready for big savings — and in extra-large quantities — with the new Costco coming to Mississauga in 2025. The sign is up, the space is being transformed, and all signs point to a grand opening later this year or in early 2026.
According to local sources and updates from the SmartCentres Meadowvale Shopping Centre, the massive retail space once occupied by RONA is being renovated to welcome a Costco Business Centre — a first for Mississauga and one of only a handful in all of Canada.

Where is the New Mississauga Costco Opening in 2025?
The new Costco will be located at Winston Churchill Boulevard and Argentia Road, right off Highway 401, within the SmartCentres Meadowvale Shopping Centre. This area is already home to popular big-box retailers like Walmart, Staples, Winners, and HomeSense — making it a prime destination for shoppers across the northwest GTA.
The former RONA building, which boasts over 810,000 square feet of floor space and ample parking, is being retrofitted to suit Costco’s needs.

What Makes This Costco Different?
Unlike the three existing Mississauga Costco locations (on Rodeo Drive, Dundas Street East, and Laird Drive), this upcoming location will operate as a Costco Business Centre.
Here’s what sets it apart:
- Tailored for businesses, restaurants, and bulk buyers
- Features larger inventory of foodservice and office supplies
- Stocked with extra-large packaging not commonly found in standard Costco warehouses
- Open to all Costco members — not just business account holders
There are currently only six Costco Business Centres in Canada, with the closest one in Scarborough. This new Mississauga location will dramatically improve convenience for west GTA businesses looking to source bulk inventory without having to cross the city.
When Will the New Costco in Mississauga Open?
While Costco does not publicly confirm store openings in advance as a matter of policy, sources close to the development indicate that most approvals and logistical steps have been completed. Construction and retrofitting are actively underway.
The expected opening timeline is:
- Late 2025 or early 2026
Locals have already spotted signage confirming the upcoming store, with the SmartCentres Meadowvale site map now including the future Costco location in the northern section of the plaza.
Why This Matters for Mississauga and Nearby Communities
The opening of a new Costco Business Centre in Mississauga signals major benefits for both residential shoppers and small business owners:
- More choice for businesses needing specialty items
- Reduced travel time for Milton and Brampton customers
- Economic boost through job creation and foot traffic in the plaza
And while it’s designed for businesses, every Costco member is welcome to shop — making it an exciting addition to Mississauga’s growing retail landscape.
Final Word: A Big Win for the West GTA
With the new Costco coming to Mississauga in 2025, residents and businesses in the northwest GTA are gaining access to a rare and specialized shopping experience. Whether you’re running a restaurant, stocking a small office, or simply buying in bulk for your family, this new location at Meadowvale SmartCentres is set to deliver big value.
Stay tuned for an official opening date — but from all appearances, Costco Mississauga Business Centre 2025 is officially on its way.
