Reitmans Canada Ltd. (TSX:RET.A). Retail. Down 14 cents, or 3.57 per cent, to $3.78 on 88,009 shares. The fashion retailer says it will eliminate 77 positions — about 10 per cent of its head office employees — to reduce costs in the face of an increasingly competitive and challenging environment and a lower Canadian dollar.

WestJet says it will use low fares to compete with new discount rival NewLeaf but that “ancillary revenue” will come only from extra fees that it thinks will “add value” for its guests and that it wont follow NewLeaf by charging passengers for carry-on baggage or for printing boarding passes at the airport.
