In the early 1970s the Canadian federal government announced that they planned to build a new super-airport on Pickering farm land north-east of Toronto. 

The government expropriated thousands of acres of farmland and houses for the airport.  Opposition grew and finally the provincial government of Bill Davis said that they were opposed to the Pickering airport, but the federal government still continues with their plans. 

The local group fighting the Pickering Airport is called V.O.C.A.L., "Voters Organized to Cancel the Airport Lands."  This is a link to their website.  Their video, that explains why they are opposed to the airport, is worth watching.
