TORONTO -- Supermarket chain Sobey's $5.8-billion acquisition of the Canadian assets of grocer Safeway will make it a leading player in Western Canada, but isn't expected to trigger price wars, analysts said Thursday.

The acquisition consolidates Sobeys' second-place ranking within the Canadian grocery retail space and as a leading player in Western Canada, analysts said.

"The western market is high-priced and we have been predicting for a couple of years that prices would begin to fall as Target builds out grocery square footage and Wal-Mart keeps pressing forward with stores," CIBC analyst Perry Caicco said in a research note.

"This deal brings lower cost-of-goods to Sobeys-Safeway and better allows them to compete. We do not see this deal, in and of itself, triggering any price wars," Caicco said.

Shares of Empire Co. and Safeway Inc. were up sharply in trading, a day after announcing that Empire's Sobeys grocery chain will buy the more than 200 Canadian Safeway stores.

Shares in parent company Empire were up 11 per cent, or $7.38, to $74.99, and shares of Safeway advanced 8.1 per cent, or US$1.88, on the New York Stock Exchange.

RBC analyst Andrew Calder called the acquisition big, but not a "game changer."

"The new, bigger Sobeys will have 1,538 stores and $24 billion of revenue (Loblaw has 1,058 stores and $32 billion of revenue)," Calder said in a note.

"But is unlikely to have a meaningful impact on overall competitive dynamics in the sector, in our view, considering what is likely to be a close review from the Competition Bureau, and Sobeys' focus on post-transaction integration and deleveraging," he said.

Calder noted the deal requires approval under the federal Competition Act, which can take up to four to five months for complex transactions.

He said he expects the Competition Bureau will take a market-by-market approach to it review, which could make for a long review given the scale and number of markets involved.

Sobeys' concentration appears heaviest in Alberta and Manitoba and it might have to sell some of the assets it will get from Safeway, Calder said.

"Divestitures would present opportunities for the other operators like Loblaw and Metro. We presume Sobeys considered this impact."

Sobeys is already the second-largest grocery retailer in Canada after Loblaw Co. (TSX:L) and will solidify that position by adding 213 Safeway stores from Thunder Bay, Ont., to British Columbia.

Sobeys currently owns or franchises more than 1,300 stores cross Canada under such banners as Sobeys, IGA, Foodland, FreshCo and Thrifty Foods.

It has not yet decided if it will keep the Safeway name.
