Vancouver Centre Liberal MP Hedy Fry is the undisputed champion of federal politics in B.C.

She's defeated all comers, including a prime minister, Kim Campbell, in her first run for office in 1993.

Since then, Fry has smacked down some of the smartest New Democrats that the party has ever fielded in federal campaigns in B.C.

They include former long-time MP Svend Robinson, UBC professor Michael Byers, and SFU professor turned mayor Kennedy Stewart.

It's been a remarkable run for Fry, especially when you consider that she's an immigrant and a woman of colour in a mostly white and Canadian-born riding.

Along the way, Fry has also faced down formidable opponents within her own party, who've wanted to snatch away the Liberal nomination.

Fry has won—get this—EIGHT consecutive elections.

She's the longest-serving female MP in Canadian history.

She's even surpassed Robinson's 25 years in Parliament, which came to an end in 2004.

But today could mark the beginning of the end of Fry's tenure.

That's because the Liberal cabinet is expected to approve the Trans Mountain pipeline expansion project.

This will increase oil-tanker traffic by nearly seven times in the waters of Burrard Inlet off Fry's riding of Vancouver Centre.

The pipeline system was bought by the Liberal government for $4.5 billion—and the expansion will cost taxpayers another $9.3 billion.

Fry has consistently outperformed expectations in elections in part because she's enjoyed such strong support from the LGBT community in Vancouver Centre.

She's been its tireless advocate in Parliament—and she's received help in this regard from Prime Minister Justin Trudeau, who apologized in Parliament for past wrongs against LGBT people.

But will that be enough when Vancouver Centre voters go back to the polls on October 21?

This time, there's a good chance that the NDP and the Greens will run candidates with deep records of service to the LGBT community.

They can tell voters: "Hey, you'll still have a community champion and I am not part of a government that wants to make English Bay a parking lot for oil tankers."

Fry has been a loyal MP to Trudeau—she stood by his side even when another Vancouver MP, Joyce Murray, sought the federal leadership.

So what does Fry get in return? A bunch of tankers threatening the beaches in her riding and a climate policy that's a cruel joke to environmentally minded voters throughout the downtown core.

She's already committed to running again.

But one thing is certain—this is likely to be Fry's toughest election yet.
