Clark announced Tuesday she intends to stay on as premier, despite a deal between the NDP and the B.C. Green Party giving the NDP support of a majority of MLAs in the B.C. Legislature.
Clark said the Liberals will follow constitutional advice and historical precedence, and test the confidence of her minority government inside the legislature.
The NDP hold 41 seats, with the Greens having agreed to add their three behind the party for any budget and confidence motions in the legislature over the next four years.
"I think British Columbians, quite frankly, are sick and exhausted of being told that the 20th-century economy is the economy of tomorrow", Weaver said at the news conference alongside Horgan.
The possibility of an NDP minority government in B.C. reopening the debate on the Trans Mountain pipeline drew reaction even before details of the party's agreement with the Greens were released.
"We're going to make sure we do as exhaustive a consultation as possible [on a potential system] between now and referendum day and the two of us, at a minimum, are gong to campaign in favour of that", said NDP leader John Horgan, alongside Green leader Andrew Weaver.
Behind-the-scenes negotiations intensified after election officials confirmed Courtenay-Comox for the New Democratic column and eventually culminated in Monday's announcement by Weaver and Horgan that they had struck an agreement to replace the government of Clark under a confidence and supply agreement scheduled to last four years.
However, unless NDP and Greens fail to enforce party discipline, Clark is nearly certain to lose the crucial vote.
"There's an very bad lot that can be done in British Columbia to stop the shipping of diluted bitumen in our coastal waters", he said.
"All of us want to hear from BC Hydro: What have you signed, how biding are these agreements and what are the consequences of proceeding?" With either the B.C. Liberals or the NDP in charge, the government would be within a single vote of defeat. But both parties say if they form government, the NDP budget will kill the tolls.
"What is most important for me in her statement was that the Premier Clark has signalled her willingness to work across party lines as we move forward".
It also outlines the legislative and policy initiatives that the NDP agrees to advance as a condition of support by the BC Green Caucus.
Horgan said the deal will also allow the province to defend coastal waters, an apparent reference to the expansion of Kinder Morgan's Trans Mountain pipeline that will result in a seven-fold increase in tanker traffic off B.C.
There's strength in numbers, and that verity was proven beyond a doubt in the so-called power-sharing agreement reached early this week by the B.C. NDP and Green Party. A New Democrat government will deliver what people voted for on May 9: "making life more affordable, fixing the services people count on, and building a sustainable economy that works for everyone", said New Democrat leader John Horgan.
The Liberals have been in power for 16 years.
Prime Minister Justin Trudeau suggested as much, too, by saying the pipeline project should proceed in spite of any political efforts in B.C.to quash the expansion.
