The federal Liberals are trailing the Tories by 13 points, while the New Democrats and Greens are enjoying modest bumps in support, a new Angus Reid poll suggests.

The randomized online survey had the Conservatives leading at 38 per cent, the Liberals trailing at 25 per cent, the New Democrats at 18 and the Greens seven points back at 11 per cent.

The Bloc, which was only polled in Quebec, drew five per cent nationally, and the Maxime Bernier-led People’s Party had three per cent support.

It also found that of the 525 respondents who claimed to have voted for the Liberals in 2015, only 49 per cent say they still support the party, with the NDP (17 per cent) the biggest recipient of disaffected Grit backers.

The survey of 1,525 Canadians was conducted from April 26-30 and Angus Reid says the margin of error for a polling sample of the kind used would come out to +/- 2.5 percentage points. However, the polling size for national preferences was 1,342 respondents.

In its previous poll in March, the Tories led nationally with 37 per cent, the Liberals were at 28 per cent, the NDP at 17, the Greens at eight and the Bloc at five.

The Angus-Reid survey also showed steady degradation of Prime Minister Justin Trudeau’s approval rating, which sunk to 28 per cent (compared to 67 per cent disapproval), though none of his rivals — save for Green Leader Elizabeth May — have above water approval rates.

Conservative Leader Andrew Scheer has a net negative rating of six (46 per cent disapproval vs. 40 per cent approval), while Jagmeet Singh is sitting at -11 (45 per cent disapproval/34 per cent approval). May has the inverse rating: 45 per cent approval to 34 per cent disapproval)/

On a provincial level, which had smaller sample sizes, the Liberals only led in Quebec (339 respondents), grabbing 28 per cent of support, though this was only two points more than the Tories. The Bloc Québécois stood in third in the province at 22 per cent, while the NDP and Greens finished at 11 and 10 per cent, respectively.

The Conservatives led in each province/region polled, while the NDP was in second place in B.C. (170 respondents), Alberta (147) and Manitoba/Saskatchewan (179), signalling Liberal fortunes have sunk in Western Canada, especially the Prairies.

In Ontario (417 respondents), the Tories led with 37 per cent compared to 32 per cent for the Liberals, 14 per cent for the NDP and 12 per cent for the Greens.
