Walmart Canada is teaming up with U.S. grocery delivery company Instacart to launch a same-day delivery pilot project in Canada.

The company said the home delivery service became available in the Greater Toronto Area Thursday, with plans to offer a similar program in Winnipeg later this month.

"By teaming up with Instacart, we're providing our customers with express home delivery of fresh, quality groceries at Walmart's low prices every day in as little as an hour,"  Lee Tappenden, president and CEO of Walmart Canada, said in a release.

The company said it will roll out the service in other markets depending  on customer engagement and adoption of the new platform. It already offers next-day delivery and grocery pick-up services in the Toronto area.

The expansion of Walmart’s home delivery service comes amid growing competition in the Canadian online grocery space.

Last November, Loblaw partnered with Instacart to offer home delivery services in Toronto and Vancouver, months after Amazon Inc. sent shockwaves through the industry by acquiring Whole Foods Market Inc.
