The leader of the Green Party says she's looking forward to doubling the size of her caucus.

Elizabeth May has not confirmed Bruce Hyer is about to join the Greens, but in an interview with reporters in Ottawa on Monday, she said she has her fingers crossed there will be good news on Friday.

“With two … obviously, we'll be able to do far more ... if, in fact that comes to pass,” she said.

“As soon as we have two Green MPs it will make a really big difference.  It will make a difference for me personally, but I think more importantly it'll make a difference for how parliament functions.”

May described Hyer as "great,” saying she worked with him on environmental issues before either of them became an MP.

She said having another Green MP would mean amendments she proposed to legislation would have an automatic seconder, instead of dying because of no support.

Green Party has little pull in northwest

A Thunder Bay political analyst is questioning whether moving to the Greens would be a winning strategy for Hyer, however.

Lakehead University political science professor Laure Paquette said changing colours may not work out for the Thunder Bay Superior North Independent MP.

"I understand that he wants to get the publicity and that would be useful for an election that's obviously coming in 2015,” she said.

“I'm afraid it's not going to make that much difference ... Even if he was NDP, it was not guaranteed he was going to get re-elected. With the Greens, his chances are not very strong," said Paquette, who added, "He has name recognition on his side."

Paquette noted the Green Party has little pull in the northwest.

"Historically, the Greens haven't attracted a lot of votes. Let's put it this way: the Green Party's going to benefit more than Mr. Hyer is going to benefit."

The Green Party recorded roughly 1,100 votes in Hyer's riding of Thunder Bay-Superior North in 2011. Hyer received 18,000 votes as a New Democrat.
