For many years, Vancouver councillors Adriane Carr and Andrea Reimer were in the trenches, fighting side-by-side on various environmental causes.

First at what was then known as the Western Canadian Wilderness Committe and then with the B.C. Greens, they advocated for better forest practices and a greener economy.

Reimer was even elected to school board as a Green trustee in 2002 and chaired the Vancouver Greens from then until 2008.

For many of those years, Carr was leader of the B.C. Greens before becoming deputy leader of the federal Greens.

But then they went their separate ways when Reimer joined Vision Vancouver in 2008, managing to get elected to city council.

Carr stuck with the Greens and finally was elected as a councillor in 2011 after several defeats in federal and provincial campaigns.

While on council in her first term, Carr was often a relentless critic of Vision Vancouver, particularly in its dealings with the development industry.

Carr also criticized Reimer's push to have the mayor appoint councillors as liaisons to different neighbourhoods.

But at the Tueday (February 7) council meeting, Carr and Reimer will be back on the same page fighting for an environmental cause close to the hearts of many Vancouverites.

Carr has filed a notice of motion seeking council's approval for a judicial review of the province's decision to approve the Kinder Morgan pipeline expansion.

The motion calls for council to "direct staff to proceed".

If the pipeline project is built, it will result in approximately 400 oil tankers travelling through the waters off Vancouver every year.

The seconder is none other than Reimer.

The notice of motion cites a 2016 B.C. Supreme Court ruling that required the province to conduct its own environmental assessment of the Northern Gateway pipeline, which was nixed last year by the federal Liberal cabinet.

Carr and Reimer point out in the motion that with regard to the Kinder Morgan project, the province "appears to have relied on environment assessments" produced by the National Energy Board.

It goes to show that politics sometimes makes for strange bedfellows.
