SNC-Lavalin's CEO is stepping down from the beleaguered engineering giant after a nearly four-year tenure that saw its stock fall by roughly half and its projects overshadowed by a political controversy tied to an ongoing corruption case. Neil Bruce, 58, will be succeeded on an interim basis by chief operating officer Ian Edwards, effective immediately. The board of directors has asked Edwards to review "the strategic direction of the company on an expedited basis" and develop a new plan "for sustainable success," the company said in a release.

Canfor Corp. (TSX:CFP). Up 64 cents, or 7.4 per cent, to $9.29. Canfor Corp. is curtailing operations at all of its British Columbia sawmills, except its WynnWood operations, due to poor lumber markets.

Canfor's operations at Houston and Plateau will be curtailed for four weeks, while its Mackenzie operations will be down for six weeks. The curtailments are scheduled to run from June 17 through July 26.
