WHAT TO WATCH THIS WEEK IN CANADIAN BUSINESS

St. Lawrence Seaway opening: The St. Lawrence Seaway is scheduled to open Monday for the commercial shipping season. There is some optimism in the shipping industry as economic growth, particularly in the U.S., could mean more traffic on the waterways of the Great Lakes. Budget time: Weeks of speculation will end Wednesday when federal Finance Minister Bill Morneau releases the government’s budget, its second since it was elected. Frustration has been building that long promised infrastructure money has been slow to flow. Morneau is also facing pressure to soothe worries about rising deficits. Ontario cap and trade: Ontario will hold its first cap-and-trade auction Wednesday. The program allows companies that surpass their caps on greenhouse gas emissions to buy credits from other businesses in order to comply. Inflation: The consumer price index for February comes out Friday.
