There might be a sign a fourth Costco store is on its way to Winnipeg.

A variance application submitted to the city's board of adjustment shows plans for a large commercial building on Winnipeg's western edge.

The project is part of Shindico's Westport Festival mixed-use development.

The proposed building is 158,163 square feet with hundreds of parking stalls, a gas bar and an area to fill propane tanks.

Pictures included show a facade which resembles Costco.

Over the last month sources have told CTV News Costco is eyeing space in the Westport Festival project.

"Real estate questions are extremely strategic. Corporate policy in Canada is, therefore, to never comment on real estate initiatives. We can neither confirm nor deny any activity in the Winnipeg market, " Costco said to CTV in early November.
