David Suzuki wrote an article today for the Huffington Post criticizing the UP Express link to Pearson:
That’s why a proposal to use diesel trains for the Air-Rail-Link plan to connect downtown Toronto with its international airport in Mississauga is concerning. A rapid transit link with the airport is long overdue, but heavy diesel trains emit particulates and other contaminants, including known carcinogens. The proposed rail line would be close to dozens of schools and daycare centres, several long-term care facilities and a chronic respiratory care hospital.
Numerous experts, including Toronto’s Medical Health Officer, have urged the Ontario government to abandon its diesel plan in favour of electric trains that could be better integrated into a region-wide rapid transit network.
