OTTAWA -- The day after the Liberals launched a new advertising blitz that took some shots at Conservative Leader Stephen Harper, the Conservatives took the wraps off a marketing blitz of their own that takes shots right back at Liberal leader Justin Trudeau.

The Tory war room had a sextet of new broadcast-ready television spots up at its YouTube channel Sunday and also unveiled a quartet of online videos featuring small business owners. All 10 of the spots take direct aim at Trudeau's economic plans.

The Liberals on the weekend released five new broadcast ads -- three for TV and two for radio -- which contrast their platform proposals with the Conservatives and while they criticize Harper, they are less hard-hitting than the Tory ads.

Notably absent from the crossfire between the two war rooms: Thomas Mulcair and the NDP. That's a sign that both the Conservatives and Liberals believe that, with two weeks to until election day, the contest for prime minister is between Harper and Trudeau.

In several polls published over the last 10 days, the NDP has faded to third place while the Liberals have advanced in some of those polls to first.

The Conservatives hope to stall or reverse Liberal momentum with sharp criticisms of Trudeau, some of it voiced by an actor, some by what the party says is small business owners themselves.

The TV ads are built around two themes, one of which is that Trudeau is "economically clueless" and the other that it is "decision time" between "higher taxes with Justin, lower taxes with Harper."

The small business videos all start with something Trudeau said in a CBC broadcast on Sept. 8: "We have to know that a large percentage of small businesses are actually just ways for wealthier Canadians to save on their taxes and we want to reward the people who are actually creating jobs."

In each video, a small business owner reads that quote back and then comments on it.

"I don't know what this man's talking about," says "Rick," identified in the video as a bakery owner from Ontario. "He just doesn't get it."

A man identified as "Shane," a bus mechanic shop owner in Nova Scotia, says, after reading that quote, "That's the furthest from the truth I have ever heard anybody ever comment about a small business. He obviously have never been in a small business."
