TORONTO -- Five things to watch this week in Canadian business:

Sino-Forest: Closing arguments continue in Toronto this week in the Ontario Securities Commission case involving Sino-Forest. Final submissions are expected from lawyers for the defunct forestry company's former CEO, Allen Chan, and others facing fraud accusations.

Energy: More than 200 global smart energy industry stakeholders, developers and service providers meet in Halifax on Monday for the 11th annual Smart Energy Event with the aim of advancing the technology in Atlantic Canada.

Valeant: The embattled Quebec-based drugmaker is expected to make a few waves next week. CEO Michael Pearson is scheduled to testify Wednesday before a U.S. Senate committee looking into rising drug prices. The company also has a self-imposed deadline of Friday to file its restated 2015 financial statements to regulators.

Bombardier: The aerospace manufacturer holds its annual general meeting Friday in Montreal as it still awaits word on whether Ottawa will pony up US$1 billion for its CSeries commercial aircraft.

Oilpatch: There's a slew of activity among companies in the hard-hit oilpatch this week. Husky Energy reports its first-quarter results on Monday, while Suncor and Cenovus are among those reporting Wednesday. And on Friday, pipeline giant TransCanada holds its annual meeting.
