Companies reporting major news:
Cenovus Energy Inc. (TSX:CVE). Oil and gas. Down 18 cents, or 0.95 per cent, to $18.76 on 1.3 million shares. Cenovus is planning a $32-million project that aims to restore the habitat of dwindling caribou populations around its oilsands sites in northeastern Alberta over the next 10 years. Decades of industry activity in the region have sliced up the boreal forest where the animals live, creating openings that make them more vulnerable to predators. The Calgary-based company has been working since 2008 on pilot projects to help protect the threatened species.
