Ontario is getting a new Costco location that's not like regular warehouses.

An official opening date has just been revealed, and you can shop at this GTA store soon.

This new Costco store will be located in Mississauga at 3115 Argentia Road, near Winston Churchill Boulevard and Highway 401.

It's close to Brampton, Halton Hills and Milton.

Since this store is a Costco Business Centre, you'll be able to find thousands of products that aren't available at regular warehouses.

Also, many products are even bigger than the already bulk-sized items you can get at regular Costco stores!

You can shop at the Business Centre warehouse with your Gold Star or Executive membership. A special membership isn't required.

Costco Canada officially announced that the new Mississauga Business Centre will open on Tuesday, October 28, 2025.

Business Centres in Ontario are open between 7 a.m. and 6 p.m. from Monday to Saturday and between 9 a.m. and 6 p.m. on Sundays.

Those shopping hours are meant to be "more convenient."

Costco hasn't revealed exactly what the new Mississauga location will offer.

But other Business Centres in Ontario have fresh meat and produce sections, deli sections, restaurant supplies, business products, office furniture, and more.

Those locations also have membership counters, auto buying programs, and business delivery options.

You can shop for pre-baked goods like English muffins, burger buns, hot dog buns, tortillas, sliced bread and bagels, and dairy items like milk, butter, whipping cream, eggs, yogurt and cheese.

Business Centres also sell cereal, coffee, tea, chocolate, candy, chips, crackers, popcorn, granola bars, condiments, spices, juice, pop, water, and more.

Specialty products like flatware, glassware, tabletop accessories, air fryers, stand mixers, mini refrigerators, tabletop griddles, blenders, and food processors are available as well.

If you don't have a Costco membership but want to get one to shop at the new warehouse, there are two options.

You can get the Gold Star membership, which costs $65 a year plus taxes, or the Executive membership, which costs $130 a year.

There are three regular Costco warehouses in Mississauga, and this location will be the first Costco Business Centre in the city.

It will be just the fourth Business Centre location in Ontario. The other three stores are in Scarborough, St. Catharines and Glouchester.

So, for anyone living or working in the western parts of the GTA, this store could be a more convenient shopping location.
