The Liberal Party of Canada holds a commanding lead among voters in Atlantic Canada, a poll released Tuesday reveals.

Halifax-based Corporate Research Associates found that 55 per cent of decided voters in the four Atlantic provinces would back a Liberal candidate if an election were held now.

That's down a point from the last CRA poll taken three months earlier, but nonetheless well ahead of the Conservative Party of Canada, which has 26 per cent support of decided voters. The NDP had 16 per cent, while the Green Party had three per cent.

CRA asked that question of 886 adults during November. The margin of error is 3.3 per cent, 19 times out of 20.

The poll also showed that the Liberals' Justin Trudeau continues to have the highest rank among the federal party leaders, at 49 per cent of those asked. That is down from 54 per cent logged during a poll taken in the late summer.

Conservative Leader Stephen Harper was the pick of 18 per cent of those polled, while 15 per cent chose NDP Leader Tom Mulcair. Green Leader Elizabeth May garnered the support of two per cent.

CRA found that the Liberals held a wide lead over the Tories and NDP in all four Atlantic provinces. Support for the party is strongest in Newfoundland and Labrador (with 62 per cent of decided-voter support) and weakest in New Brunswick (with 49 per cent).
