Prime Minister Stephen Harper and the Conservatives continue to gain momentum in the spring election campaign, according to the latest survey.

The Nanos poll, commissioned by CP24, CTV, and the Globe and Mail, shows that as of Friday, April 1, support for the Conservatives has increased slightly, putting them ahead of the Liberals with an 11-point lead with 41.3 per cent of the vote.

Quebec is where the Tories made most of their gains. At the beginning of the campaign, Conservative support in Quebec was at 19.6 per cent. Now, it stands at 26.7 per cent.

The new numbers mean the Conservatives have topped the 40 per cent mark -- a number that puts them within reach of a majority government.

Support for the NDP dropped by 4 per cent to 16 per cent while the Liberal Party gained four points to 30.3 per cent.

The poll also showed that Canadians are mostly basing their vote on the party's policies. About one in two Canadians (52 per cent) listed policy as the vote driver. About 22 per cent said they are voting based on the party's leader.

The poll was conducted between March 30 and April 1, with a random telephone survey of 983 decided Canadians. The margin of error is 3.1 percentage points, 19 times out of 20.
