Hi Mark,
Thanks for clarifying your question about connecting the Finch and Eglinton Crosstown LRTs at Pearson Airport. Metrolinx is currently working with the City of Toronto, the City of Mississauga and Pearson Airport to plan for the extension of the Eglinton Crosstown LRT to the airport. Extension of the Finch LRT to Pearson Airport is protected for in the design and the currently planned terminus at Humber College. While detailed planning has not yet been done for this extension, we know that it would be complex and costly infrastructure because it would span the Humber Valley. Meanwhile, Pearson Airport is planning for potential reconfiguration of their terminals and ground transportation access, which could change the connections between terminals (

As these plans move forward, Metrolinx, along with our partners, will certainly be examining all opportunities to better connect transit services and provide new mobility opportunities, including looking at how people move around the airport.
Thanks again for reaching out and I hope this answers your questions.
Have a great day
Regards
