Most actively traded companies on the TSX, TSX Venture Exchange markets

TORONTO – Some of the most active companies traded Wednesday on the Toronto Stock Exchange and the TSX Venture Exchange:

Toronto Stock Exchange (12,412.73 down 56.59 points):

Bombardier Inc. (TSX:BBD.B). Transportation equipment. Down 10 cents, or 2.04 per cent, at $4.80 on 14.92 million shares.

Air Canada (TSX:AC.B). Airliner. Up 53 cents, or 25 per cent, at $2.65 on 10.37 million shares after second-quarter results beat analyst estimates prompting a National Bank Financial analyst to raise his rating to outperform and increase his target price by 25 per cent to $3.75. Air Canada also recorded its best second-quarter revenue in its history: $3.06 billion versus $2.99 billion last year while its loss narrowed to $23 million from $161 million.

Athabasca Oil (TSX:ATH). Oil explorer. Up 75 cents, or 10.18 per cent, at $8.12 on 6.76 million shares. Alberta’s energy regulator approved its Dover oilsands project, which will use steam to soften the bitumen and draw it to the surface. The approval means its joint-venture partner, PetroChina, has a month to buy Athabasca’s 40 per cent stake in the project for $1.32 billion.

Potash Corp. of Saskatchewan (TSX:POT). Fertilizer producer. Up 33 cents, or 1.08 per cent, at $30.87 on 5.57 million shares. The company’s stock price is slowly creeping up after major losses last week. Potash companies have been on the spotlight since Russian producer Uralkali announced at the end of July that it will pull out of a marketing consortium, which will result to lower potash prices.

Yamana Gold Inc. (TSX:YRI). Miner. Unchanged at $9.31 on 3.49 million.

Toronto Venture Exchange (907.13 down 5.70 points):

Fission Uranium Corp. (TSXV:FCU). Uranium explorer. Up a penny, or one per cent, at $1.01 on 4.74 million shares.

Company reporting major news:

Boralex (TSX:BLX). Renewable energy. Down two cents, or 0.18 per cent, at $10.90 on 13,279 shares. The renewable energy producer says construction of its Quebec wind farm remains on schedule despite a one-week shutdown caused by a general strike in the province’s construction industry in June. The Montreal-based company posted better than expected second-quarter results, helped by an acquisition in France and better weather conditions.

Valeant Pharmaceuticals International Inc. (TSX:VRX). Specialty drug. Up $2.12, or 2.13 per cent, at $101.70 on 827,677 shares. The Laval, Que.-based company revised its 2013 outlook upwards to between $6 and $6.20 per share, up from $5.55 to $5.85 and is looking to push ahead with small acquisitions following its recent $8.7-billion mega deal to buy Bausch + Lomb. Second-quarter profits totalled $10.87 million, up significantly from a $21.61-million loss the year before. Sales jumped 34 per cent to $1.1 billion
