Green Leader Peter Bevan-Baker speaks at the provincial leaders debate Summerside, P.E.I. on Tuesday.

After a brief provincial election campaign devoid of drama, voters on Prince Edward Island appear poised to stir things up and make some history when they cast their ballots Tuesday.

The Island's Green party, led by Scottish-born dentist Peter Bevan-Baker, has recorded upward momentum in the polls for more than a year, suggesting the smallest province may be ready to elect Canada's first Green government.

"It has not been a particularly fascinating campaign, but I think it's going to be a fascinating election night," says Don Desserud, a political science professor at the University of Prince Edward Island.

"There's something going on here. You can't deny that after a whole year of solid numbers for the Green party that they've attracted attention and are being regarded with great favour."

A Narrative Research poll for the Charlottetown Guardian released this week suggests the Greens had maintained a lead, but it was within the margin of error and the Tories and Liberals were not far behind.

The close numbers also raised the spectre of a minority government, which would itself mark a historic moment for the Island: The last time a minority was elected in P.E.I. was 1890.

Islanders have been electing either Liberal or Conservative governments since Confederation. And a clear pattern has held since the mid-1960s, with majority governments being regularly replaced after serving three terms — though the Liberals eked out a fourth term in 1978, only to lose power a year later.

Premier Wade MacLauchlan's Liberals will be seeking a fourth term on April 23, which has prompted some critics to suggest the party has overstayed its welcome.

So what is it about the Greens that has moved the Island's traditionally small-c conservative voters to consider a more progressive party?

Bevan-Baker says the shifting political sentiments on P.E.I. are a reflection of a broader movement away from traditional, mainstream politics. He's called it the local expression of a global phenomenon.

"People are looking for something that doesn't sound or smell or taste like a conventional politician," he said in an interview late last year.

Bevan-Baker became the first member of the Green party to win a seat in the P.E.I. legislature in 2015, having failed to win a single election after 10 attempts on the Island and in Ontario.

As party leader, he has spent the past three years carefully crafting the party's brand by consistently challenging the notion that the Greens are a single-issue entity devoted only to environmental activism.

When it comes to climate change and carbon taxes, Bevan-Baker has been careful to link a healthy environment with a prosperous economy.

On Tuesday, voters will also learn the results from a binding referendum on electoral reform, which will determine if Islanders want to keep the first-past-the-post system or change to a mixed-member-proportional-representation model.

In a 2016 plebiscite, 52 per cent voted in favour of switching to a mixed-member system, but MacLauchlan rejected the results, saying the 36 per cent turnout rate was too low.

Prime Minister Justin Trudeau promised to abolish the first-past-the-post system federally during the 2015 election, but he later abandoned that pledge, saying Canadians were not eager for change. Voters in British Columbia rejected making such a change in December 2017.
