The Alberta legislature was a busy place Saturday afternoon as federal NDP Leader Tom Mulcair and Liberal Leader Justin Trudeau paid separate visits to Premier Rachel Notley.

In a brief media availability after their meeting, Mulcair and Notley said they found common ground on issues of mutual concern, including energy issues.

Federal Liberal Leader Justin Trudeau smiles at the media as a sheriff leads him to the office of Alberta Premier Rachel Notley Saturday. (CBC ) "Our view is that we are an energy-producing province and we need to respect that and focus on developing that in a responsible way," Notley said. "Because jobs and job creation, not only for Albertans but for all Canadians, is critical."

Mulcair said natural resources need to be developed responsibly and said that value-added jobs "are the way of the future."

He said Canada needs a credible and open system of assessing the environmental impact of proposed projects.

"If we want to make sure projects can go ahead, we have to make sure that the process is fair and that people can feel confident in it," he said.

Trudeau did not hold an availability after his meeting with Notley.

Trudeau and Mulcair were in Edmonton to address the annual general meeting of the Federation of Canadian Municipalities. Trudeau made a keynote address on Friday; Mulcair's turn came earlier Saturday afternoon.
