Weaver said the Greens are open to talking to both the Liberals and New Democrats about governing, but until the votes are counted it's too early to discuss political deals.
Horgan told reporters he meant to wait for the election's final outcome on May 24 before talking further about government scenarios, adding he would be willing to work with any party.
As the incumbent premier and with the most seats, Clark would be expected to get the first opportunity to form a minority government with the support of the Greens, who finished one seat short of gaining official party status in the legislature.
While saying the Green Party is focused on good policy and will work with either party, it certainly sounds like party leader Andrew Weaver has more in common with the NDP than the Liberals.
It's not easy being Green on British Columbia's political scene - especially for a party facing a hard choice in who it might back in a minority government.
Kathryn Harrison, also a political science professor at UBC, said the Greens must weigh the risks of either choice but the Liberals may wait to do any negotiating until the final ballot count is released, which must happen by May 24.
The NDP won one riding by only nine votes, making a recount a certainty that will determine the difference between a minority and majority if it were to flip to the Liberals.
Interim Conservative leader Rona Ambrose suggested Wednesday she's anxious what the British Columbia election result means for Kinder Morgan's Trans Mountain pipeline, with the possibility the Greens could help the NDP form a minority government.
"This campaign has always been not about me, but about us, on the Us Bus", Horgan said. He said voters want changes to political fundraising laws and electoral reform - two of the Green party's priorities.
Looking forward, Angolano said all three parties need to face how to cross that urban-rural divide in the next election to form a majority government.
BC Liberal candidate, Tom Shypitka took 57 per cent of the vote share with 9114.
The campaign began four weeks ago with Clark and the Horgan locked in a tight race to be premier, and Weaver hoping to build upon his one seat in the legislature.
"I think we could see a compromise position there", he said.
An NDP government in B.C., bolstered by the Greens, is not the preferred option.
"B.C. Greens are committed to working with whichever party we end up working with", he said.
"Voters know best. And they reminded us tonight that we are far from ideal", Clark said.
When the campaign kicked off April 11, the Liberals held 47 of the Legislature's 85 seats, the NDP had 35, the Greens one and there was one independent.
Pipelines: The Greens do not support the Kinder Morgan Trans Mountain pipeline expansion project and will work to stop it from proceeding. 44 is the magic number needed to control the 87-member British Columbia Legislative Assembly, which meets in Victoria.
A return of the BC Liberals tonight under Clark would largely maintain course, amid some promises to reduce MSP premiums and cap tolls on the Port Mann and Golden Ears bridges. British Columbians voted for action for action on climate change. As she left the polling station, Clark stopped to say hello to a young girl.
Or it could be a B.C. Liberal MLA missing a confidence vote for the government to be defeated.
A Houston-based pipeline builder, Kinder Morgan, wants to construct an 848,000-barrel-a-day pipeline to bring oil from Alberta's tar sands to a terminal in urban Burnaby, just east of Vancouver.
