Green Party leader Elizabeth May on Tuesday became the first federal party leader to make a campaign stop in Calgary, where she said other party leaders shouldn't take the election outcome in Alberta and Calgary for granted. Ms. May hung out at Stephen Avenue Mall, surrounded by green-shirted supporters, playing road hockey and talking to voters. She said the Green party is set to make substantial gains in Alberta because the province is being forgotten on the national stage and her party has a family-oriented platform.TODD KOROL/Reuters
