Lindsay Meredith, part of SFU's Beedie School of Business and an expert in political strategy and marketing, called Green party leader Andrew Weaver the "king maker" should the current 43-41-3 seat ratio stand, between the Liberals, NDP and Greens, respectively.
There will be at least one recount after the NDP won in Courtenay-Comox but just nine votes.
British Columbia Premier Christy Clark's Liberal Party was neck to neck with the left-leaning New Democratic Party in an election that could spell uncertainty for multibillion-dollar energy projects. "And it's something that I think could be very exciting for the future of our province".
The final results of British Columbia's election are still not in, but already experts are predicting an unstable government that is unlikely to last a full four-year term.
Liberal Premier Christy Clark, her party having held power for 16 years, came close to another majority - albeit one seat shy.
But the Liberals could also ask the Greens to form a coalition or working agreement, said political science professor, Kathryn Harrison. And here tonight, we have been presented with an opportunity by British Columbians to open a whole new dialogue in our province, in our legislature. "British Columbians voted today for proportional representation". NDP's Mitzi Dean has taken the lead with the Liberal and Green candidate splitting the remaining votes.
Horgan was non-committal about a possible coalition with BC Greens, but didn't waste time drawing similarities between the two parties. We are the first Green caucus elected in North America.
After his speech, Weaver said he called Clark and Horgan to congratulate them on their campaigns and "start the conversation on the next steps for our province in the days ahead".
Historically, the delayed counting of absentee ballots has meant only minor changes in final results.
"It could be some time before this is completely clear".
The unofficial results showed Liberals finished with 40.85 per cent of the popular vote, down about four per cent from 2013.
The NDP focused its campaign on the seat-rich Lower Mainland. The NDP also do not support the pipeline project.
Horgan and Clark have drawn different lessons from Tuesday's results.
Several Liberal cabinet ministers lost seats in Metro Vancouver, including Attorney General Suzanne Anton, Technology Minister Amrik Virk and Peter Fassbender, the minister responsible for TransLink. In B.C., the party got a campaign bus for the first time in this election. The Green and NDP got out their vote while many Liberal voters were not as motivated and opted to sit this one out.
But asked whether he believes his party's priorities more closely align with the NDP than Liberals, Weaver dodged the question, noting that he has meetings planned with the leaders of both parties. Under the watch of Clark, a former radio host who's governed for six years, BC has led Canada in job creation and posted a budget surplus for five consecutive years.
"We're starting negotiations tomorrow", said Green Party Leader Andrew Weaver, calling the election "a historic day for British Columbia".
"If you can make the counterfactual argument that the Greens are closer to the New Democrats [and] a few extra votes would have made a difference, there aren't too many places where you could make that".
They previously brought forward legislation banning union and corporate political campaign donations on seven occasions, only to see it squashed by the Liberal majority.
