The Project

For decades, it’s been clear that Toronto has needed a dedicated air-rail link. But by 2031, Toronto Pearson and Union Station are expected to serve 190 million travellers a year – that’s almost double the volume of traffic today. That’s more cars, more gridlock and plenty of missed flights.

The Union Pearson Express changes that future – and we’re almost there. The construction of an air-rail link between Toronto Pearson International Airport and Union Station in downtown Toronto is almost complete. Here are a few details on one of the most ambitious – and important – transportation projects in the province’s history.


New Line

A key element of the Union Pearson Express was the construction of a new connecting line between the existing GO Kitchener rail corridor and Terminal 1 at Toronto Pearson International Airport. Construction on the three-kilometre spur line sees the UP Express rise above major highways and roadways. With a highest elevation of about 28m above ground, the trip will give visitors and residents a uniquely elevated view of Toronto Pearson and the city. Find out more...



A special air-rail service calls for special vehicles. For the Union Pearson Express, new shuttles were required to meet the unique operating environment of the airport. The Diesel Multiple Units (DMUs) we’ve selected meet exacting vehicle performance and design specifications, and conform to the most stringent air quality requirements. Find out more...



From the time they buy their tickets to the time they board our state-of-the-art shuttles, Union Pearson Express guests enjoy the benefits of convenient, well-designed and accessible facilities. Among those are our four stations – new sites at Union Station in downtown Toronto and at Toronto Pearson Terminal 1, and significantly upgraded stations at Bloor and at Weston. Find out more...




The Union Pearson Express service required upgrades and changes all along the shared 22-kilometre stretch of the GO Kitchener line between Union Station and the connecting line to Terminal 1. In fact, those upgrades are part of a larger infrastructure project – the Georgetown South Project. Find out more...


In the Community

Metrolinx and the Union Pearson Express are committed to keeping our partners in the community informed and engaged in the development of the project. We regularly provide updates and information on project status on our website and in newsletters available to stakeholders. We have also conducted community outreach and plan to increase our engagement in neighbourhoods as launch approaches. Information is available through three community offices – at Strachan, Weston and West Toronto Diamond – which offer interpretation services in more than 100 languages.

Getting from Union to Pearson

Travelling between downtown Toronto and Toronto Pearson International Airport is about to get a whole lot easier. It's time to rise above the traffic and experience stress-free reliability.
