A spat between the mayor and the Canadian Home Builders Association has thrown a wrench into several council committees.

The head of the home builders association says statements made by the city's head planner basically amount to a freeze on development.

The mayor responded by having his chief of staff fire off a letter to the home builders group demanding an apology and suspending them from several working committees.

Charron Ungar, the head of the home builders, says he has nothing to apologize for.

“I stand firmly behind the statement that I made at that dinner and I have no intention and I've already stated that I will not apologize for my comments,” said Ungar.

“When you are representing an important partner for the city, when you sit on the committees that have the information but you choose to spread different information to thousands of people, that's what I object to,” said Mayor Naheed Nenshi.

On Monday, council went behind closed doors to discuss Nenshi’s letter to the homebuilders.

In the end they directed the mayor to meet with the group to try and work out their differences. 

The meeting is scheduled for Tuesday.
