The Union Pearson Express between Toronto Pearson International Airport and Union Station downtown was a hot political issue in Weston.
It had originally been proposed for completion by 2009.
Weston is currently a station stop on the Kitchener line operated by GO Transit and additional airport trains would stop there.
The link would see the construction of three additional tracks through the neighbourhood and increased rail traffic more than fourfold.
Community activists worried about how the link would sever the community (vehicle traffic on John Street will be permanently blocked from crossing the tracks, replaced by a pedestrian bridge) and the possibility of lower future property values due to increased noise and diesel fumes.

It was an issue during the Canadian federal election held on January 23, 2006, when incumbent Liberal Member of Parliament, Alan Tonks, supported the link, while the other candidates opposed it.
It was also an issue in the February 2007 provincial by-election, where all local candidates came out against the link, but which was still supported by the governing Liberals.
The Weston Community Coalition (WCC) had proposed a subway line as an alternative to run through the Weston rail corridor to the airport that would have stops along the way which would serve many communities throughout Toronto and be operated by the TTC rather than a private company.
Various other alternatives were presented by community activists such as an Eglinton subway to the airport, an LRT alternative, or a route down Highway 427.

In the end, the tracks went into a trench with bridges overhead to prevent bisecting the neighbourhood.
  A "rail deck park" allowed the expansion of a Toronto Catholic school playground over the tracks.
