This morning at 8:20 a.m., NDP Leader Tom Mulcair will try to inject momentum into his campaign with a public event at the Bear Creek Pavilion in Surrey.

The location at 13700 88 Avenue is on the boundary of the federal ridings of Surrey-Newton and Surrey Centre and not far from Fleetwood-Port Kells, which begins seven blocks to the east.

At the start of the campaign, the NDP appeared poised to take all three seats.

But as Mulcair's polling numbers have declined, incumbent New Democrat Jinny Sims finds herself in a tough fight in Surrey-Newton.

The former B.C. Teachers' Federation president is facing former Liberal MP Sukh Dhaliwal and well-known broadcaster Harpreet Singh, who's running for the Conservatives.

In Fleetwood-Port Kells, the NDP is running former RCMP inspector Garry Begg against Conservative incumbent Nina Grewal and Liberal Ken Hardie.

In Surrey Centre, incumbent New Democrat Jasbir Sandhu is trying to keep his seat against Conservative Sucha Thind and Liberal Randeep Sarai.

The website threehundredandeight.com has projected the Liberals as being likely to win Surrey-Newton and in a good position to take Fleetwood-Port Kells. The NDP is projected to win Surrey Centre by a narrow margin.

The website cautions that its numbers "are not polls and are not necessarily an accurate reflection of current voting intentions in each riding".

The Conservatives recently tried to shore up their support in North Surrey by promising to invest $700 million in a proposed $2.1-billion light-rail network linking Surrey Centre with Newton, Guildford, and Langley City. The province has promised to provide another one-third of the cost, leaving TransLink or the City of Surrey to try to figure out ways to come up with the remainder.

The New Democrats have pledged $5 billion in new transit funding to the Lower Mainland over 20 years. Mulcair says this can be accomplished by transferring an extra penny per year in federal gas taxes to the region.

The Liberals have promised to spend $5 billion on new infrastructure, including transit, next year.

Meanwhile, Mulcair has taken a strong stand against the recently negotiated Trans-Pacific Partnership, setting his party apart from the Liberals and Conservatives.
