Plans to locate an Urgent Care Centre on the 6.2-acre former Grace Hospital site have changed.
As a result, the city is calling for "Expressions of Interest" on the site.
Windsor Mayor Drew Dilkens says the notification will formally be issued on Monday and developers will have 60 days to respond.
He says there had not been a sale agreement for the urgent care use.
"City Council had reserved that particular site in the discussion and in the context of the hospital redevelopment plan. So that was to be the home of the proposed emergency centre."
But Dilkens adds there is a wide opportunity for use of the Grace site.
"There's some zoning already in place for the Grace hospital site that speaks to commercial, at least some, commercial application at the University Ave. frontage and then of course it can be residential behind. We would look at what the possibility is for a strong mixed use development."
