Bob Rasmussen's right - Olivia Chow (and Jack Layton) have been steadfast in their opposition to airport expansion and in their support for devolution of control of the Port Authority to the City: the imposition of the federally controlled Port Authority on Toronto was never justified by the criteria set out in the Canada Marine Act for Port Authorities, and that unilateral imposition of the Port Authority regime onto Toronto’s waterfront created the monster that is the ever-expanding Island Airport.
Bob Rae has publicly indicated his support for devolution. Here is our question of candidates in the 2008 byelection, and Bob’s response:

Question:

The Toronto Port Authority operates a port that is neither self-sufficient , or “of strategic significance to Canada’s trade” as required for designation as a Port Authority under the Canada Marine Act. In fact, the port has consistently lost huge sums - $4,610,000  in 2006 (2005: $3,366,000), on income of only $9,913,000 (2005: $9,686,000). These losses were incurred from the actual operation of the port, and from the Toronto Port Authority’s airport operation. Losses of this magnitude have been consistently incurred every year since the Toronto Port Authority was established. The only cargos handled by Toronto’s port do not require the Port Authority overhead – cement, gravel, sugar, and salt, for local use, delivered directly to private wharves.

As there is insufficient national interest to justify continuing federal government control, through its five appointees to the board of the Port Authority, of hundreds of acres of prime waterfront land (including 215 acres currently occupied by the Island Airport), Community AIR, and others have called for the federal government to relinquish control of the TPA, and permit the City to appoint five of its seven directors.

Answer from Bob Rae: I believe the Toronto Port Authority should be devolved to the City of Toronto.
And Michael Ignatieff has been a consistent opponent of Island Airport expansion. Here’s his statement from the 2006 federal election:

CommunityAIR is working hard to fight for a clean, green waterfront. I support the proposal to close the Island Airport so that this land can be restored to its zoned use for public open space. I believe this is an opportunity we can all work together to achieve.
In meetings we have had since with both Rae and Ignatieff, they have confirmed these views.

CommunityAIR works with both NDP and Liberal politicians to bring an end to the Tory-dominated TPA’s oppressive rule of our waterfront.
