Winnipeg Mayor Sam Katz and his wife, Leah, are expecting a baby.

Katz told CBC News the baby's due date is in December.

He and Leah married in April 2011.

Katz has two daughters from a previous marriage to Baille Burke. They divorced in 2006.

The mayor said he's over-the-moon excited about the soon-to-be newest member of his family. But in family life, just like in politics, not everyone agrees on what they want.

"The biggest challenge we are going to have is our oldest Ava, who is 11, wants a boy and our youngest, Kira, who's seven, wants a girl," he said.
