The latest debate involving the three main mayoral candidates was held at the ZoomerPlex in Liberty Village.

John Tory, Olivia Chow and Doug Ford discussed a number of issues during their two-hour appearance on the New AM 740’s Goldhawk Fights Back, including , traffic, transit, taxes, spending and teamwork.

But it was the question of integrity that struck a raw nerve.

Chow is demanding Tory declare a conflict-of-interest before election day, on one of the most important issues the next council will likely face —the possible expansion of the Island Airport.

One of Tory’s sons is the CEO of an airline company that has a regional office there and he’s repeatedly lobbied in favour of expansion.

When pressed on the matter by Chow, Tory told the studio audience and those listening on radio, ”I will follow the rules, with respect to my son or a thousand other things that could go on.  I will follow the rules … I’m not elected yet.  I’m working hard to get elected but I’ll follow the rules.  Period.”

The Municipal Conflict of Interest Act states the interest of a councillor’s spouse or child should be considered the councillor’s interest.
