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

Earnings: In a true sign that spring has sprung, several companies across an array of sectors begin reporting first-quarter earnings this week, including Rogers Communications on Monday, and grocery chain Metro, Canadian Pacific and AltaGas on Wednesday.

Manitoba votes: The province heads to the polls for Manitoba's election on Tuesday. Greg Selinger, the province's NDP premier, has been on the hot seat over his decision to raise the provincial sales tax, and Brian Pallister's Tories are atop the polls.

Partnerships: The Canadian Club of Ottawa hosts a panel discussion Tuesday on how partnerships between governments, industry and NGOs are becoming commonplace. Jaak Peters of Johnson & Johnson is among those scheduled to appear.

Bank of Canada: Central bank governor Stephen Poloz and senior deputy governor Carolyn Wilkins are on Parliament Hill this week, appearing at a House of Commons finance committee on Tuesday and before the Senate's banking, trade and commerce panel on Wednesday.

StatCan: The federal agency releases wholesale trade figures for February on Wednesday and retail trade and inflation numbers for March on Friday. Inflation slowed in February, largely driven by a significant drop in the price of gas.
