Nov 13 (Reuters) - Loblaw Cos Ltd, Canada's largestgrocer, reported a 29 percent fall in quarterly profit, hurt bya later Thanksgiving holiday and a decline in sales at itsdrugstores.
The Thanksgiving holiday in Canada fell on Oct. 14 thisyear, nine days after the company's third quarter ended.
The holiday was on Oct. 8 last year, just two days after thequarter ended, meaning the company got some benefit fromshopping ahead of the holiday.
Loblaw cut its full-year earnings outlook due tohigher-than-expected investments in store expansions and certainfood categories as competition intensifies.

Earlier last month Loblaw, which is also involved infinancial services and property leasing, said it was cuttingabout 275 jobs as part of its drive to improve operations.
Third-quarter net income fell to C$154 million ($147million), or 55 Canadian cents per share, from C$217 million, or77 Canadian cents per share, a year earlier.
Excluding certain one-time items, profit was 73 Canadiancents per share, below analysts average estimates of 80 Canadiancents, according to Thomson Reuters I/B/E/S.
