The Liberals have until August to call a byelection, but local riding officials from all the major parties are not waiting for the premier to choose a date.

It's been one month since Dwight Duncan formally resigned his seat at Queen's Park. Since then, Premier Kathleen Wynne has taken the reins of the Liberal party and she's confident it will retain the riding of Windsor-Tecumseh in an upcoming byelection.

But University of Windsor political science professor Lydia Miljan says it's anybody's seat to win.

"I think that it's going to be a very competitive race, much more so than anything we've seen in the past," says Miljan.

Anyone's seat and yet no candidates have been officially chosen by the front-running respective parties. Both are in the process of identifying potential candidates.

“We've had a number of people step forward and put their name in the hat for a nomination," says Patrick Hannon, president of the Windsor-Tecumseh NDP Riding Association.

Current Windsor city councillor Percy Hatfield is holding a news conference Friday afternoon to announce whether he will seek the party's nomination.

Andrew McAvoy, who took on Dwight Duncan in the last election, will also seek the nomination for the NDP.

"It will be a contested nomination," says Hannon.

The Liberals are also on the hunt to fill Duncan's shoes.

“We have about four or five interested parties, some who have come to us, some who we've reached out to." says Liberal Windsor-Tecumseh riding president Milan Stipic.

CTV News has learned three of those names, including the former CEO of Windsor airport Federica Nazanni, Michael Duben who's an executive at Enwin Utillities and the owner of Unconquered Sun Sean Moore.

Both the Liberals and the New Democrats say they hope to have a nomination vote in the next two weeks.
