NDP and Liberals start their election engines

It's back-to-work time for MPs returning to Parliament Hill after the summer break, and with the election countdown clock ticking, parliamentarians are shifting into overdrive. 

Both the Liberals and the NDP held their national caucus meetings earlier this week to discuss top priorities for the fall session.

With the Liberals approaching their fourth year in government, chief government whip Mark Holland said they won't be straying too far from their economic agenda. 

"What I hear at the doors is infrastructure, I hear the economy, I hear people talking about their kids. Those are the top line issues," Holland said.

The NDP are also choosing to focus on traditional bread-and-butter issues for the party.

"Certainly the issues are the same issues the New Democrats have always tackled," the NDP's caucus chair Matthew Dubé said, such as NAFTA, opposition to pipelines, and affordable housing.
