From Inside Toronto December 15, 2009:

…Miller said in general, the conference has confirmed for him that Toronto is on the right track environmentally. Although he noted that Copenhagen is much more bicycle friendly than Toronto. And he was impressed with the larger reliance on wind power.

When asked where he would like to see more windmills in Toronto, Miller replied that the Island airport would be a good spot.

"It's right in the middle of a wind tunnel - it would be a perfect place to provide green energy and once you have a rail linking the downtown to the airport you have no transportation reason at all to have an airport downtown," he said.
