The Greens appear to be replacing the NDP in New Brunswick, much like they have in neighbouring Prince Edward Island, according to a new poll by Mainstreet and iPolitics.

The provincials Liberals had the support of 35 per cent of respondents, the Progressives Conservatives had 21 per cent, the Greens ended up with 11 per cent and the NDP have 5 per cent.

“They’ve really changed positions — the Greens are now the NDP,” said Quito Maggi, president of Mainstreet Research, an Ottawa-based polling firm.

New Brunswick is one of the few parts of Canada where the Green Party has seats, the others being PEI and British Columbia. The B.C. Greens won three seats in the May 9 election and are on the cusp of playing an unprecedented role in that provinces thanks to an alliance with the NDP. The NDP-Greens are expected to replace the current Liberal government any day now.

N.B. Green Leader David Coon is the most popular New Brunswick political leader, according to the poll. He already has a seat in the legislature.

In P.E.I., Green Leader Peter Bevan-Baker also has a seat. Maggi said the Greens have similarly taken support from the NDP in that province.

In a regional breakdown, the poll found that the Greens have a tremendous amount of support in the Fredericton region.

They lead with 33 per cent of voters in the provincial capital, with the Liberals and Progressives Conservatives trailing at 30 per cent.

But calculating how support for the Greens plays out in the seat count is tricky because voters in different provinces might be leaving different parties, said Maggi.

“(In B.C.), everyone assumed that the Greens were really splitting votes with the NDP, but as it turns out they were actually taking a lot of votes from the Liberals,” he added.

“If it’s a similar pattern in New Brunswick, who knows how that’s going to affect voter patterns and seat counts.”

The B.C. Liberals are further to the right than the New Brunswick Liberals, though Fredericton is typically a place with Progressive Conservative support.

An election isn’t expected until next year in New Brunswick, though Quito said there have been rumours of an early call.

Premier Brian Gallant and the Liberals would have a major lead if that were to happen, though 28 per cent of poll respondents say they are undecided.

Mainstreet contacted 1,500 New Brunswick residents over June 21 and 22. The poll has a margin of error of plus or minus 2.53 percentage points, 19 times out of 20.

Ahead of the 2014 election, Gallant also had a large lead that was cut down by incumbent David Alward and the PCs.

“It ended up being not neck-and-neck, but pretty close at the end,” said Maggi.

Mainstreet also polled federal attitudes and found Prime Minister Justin Trudeau and his Liberals are still flying high with 48 per cent support across the province.

The Liberals swept the Maritimes and Newfoundland and Labrador in the 2015 election.

The Conservatives are second with 21 per cent, though they only elected their new leader — Andrew Scheer — on May 27.

Spelling trouble for the federal Greens is widespread support for TransCanada’s Energy East pipeline and a carbon tax.

Seventy per cent of respondents said they support the pipeline, compared to 22 per cent who said they opposed the project, which is currently before the National Energy Board for its permits.

Fifty per cent of respondents oppose a carbon tax, while 44 per cent support it, the poll found.

The New Brunswick government is still considering how it will meet a coming federal requirement for every province and territory to have a carbon pricing scheme in place by 2018.

“(New Brunswick residents) are going to hold accountable more the provincial government for some of those things and not really hold the federal government to account for the role they play in that,” said Maggi.
