Toronto, Ontario

The Greenbuild 2011 International Conference and Expo ended on a warm, sunny afternoon in Toronto Friday with a closing plenary featuring New York City Mayor Michael Bloomberg and the Bay Area's John Picard, principal of Picard & Associates.

Those flying home for the weekend met with long lines and one to four hour delays at Toronto Pearson International Airport as union security screeners orchestrated a maddening "work-to-rule" protest against Garda World Security Corp., and by extension, thousands of innocent travelers at Canada's largest airport.

A high-profile reception hosted by SCIenergy at the recently completed and groundbreaking 18 York building included several ice scupltures, one of which was the long open bar. The event doubled as a launch party for Enlighted, a Sunnyvale, Calif.-based lighting sensor company that recently closed $14 million in funding.
