WINNIPEG -- Winnipeg City Council has voted to delay the Polo Park development vote by one month.

During a council meeting on Wednesday, the decision to delay the vote was passed with a 12-4 vote.

This news comes after a move by the Winnipeg Airports Authority late Tuesday night, saying in the name of the Government of Canada, it objects to the plan to allow housing to be built at the old stadium site and at the mall.

The WAA has raised concerns more housing in the area could jeopardize its 24-hour operations because of the potential for more noise complaints.

Mayor Brian Bowman spoke on Wednesday afternoon about the decision. He said he can't say much as the hearing process is continuing.

He also noted there was some concerning behaviour, as one council member introduced new information. Bowman said this goes against the rules.

"With the hearing process and the rules governing hearings at city hall, members are not permitted to consider new information," said Bowman. "We had at least one member of council, councillor (Kevin) Klein, according to the speakers and our clerks, introduced new information and was ruled out of order."

Bowman said he asked the clerks to reach out to councillor Klein and all councillors to remind them of the rules for hearings.

"I know there is a lot of parties that have significant interest in this matter and I would remind everybody, whether it’s the province, the developer, the airport, members of council, to please respect the rules governing hearings at city hall throughout this process."

Bowman added that he wouldn't add additional commentary until the hearing is complete.
