Sunday marks the final day for shopping for one of two McNally Robinson bookstores in Winnipeg.

Doors to financially troubled McNally Robinson's store at Polo Park Shopping Centre will officially close at 6 p.m. CT.

The Winnipeg-based independent book chain filed for bankruptcy protection last week under the weight of more than $2.5 million in losses in its 2009 fiscal year.

When the doors are locked on Sunday, 175 people will have lost their jobs.

A recent expansion site in Don Mills, Ont. closed Dec. 28, the day the bookseller went public with news of its bankruptcy and restructuring effort.

The Toronto store opened in April, while the Polo Park store opened in 2008. Like all McNally locations, the stores contained a Prairie Ink Restaurant and Bakery.

The firm's flagship location at Grant Park Shopping Centre in Winnipeg will remain open, along with a store in Saskatoon.

The company is blaming the economy, advancements in technology and internet shopping as reasons for its current financial misfortunes.

"Booksellers in Canada are currently working against serious headwinds: recession, stagnant book prices, steep discounting and increasing competition from internet sales and electronic-text formats," the company said in a Dec. 29 news release.
