Windsor Mayor Eddie Francis claims that 10-20 planes have been serviced by Premier Aviation at the maintenance, repair and overhaul hangar on land next to Windsor International Airport.
During a media conference Wednesday, the mayor said he recently met with Premier executives.
Francis said the company likes keep matters private because of competition in the industry.
"They have many clients. There's a strong demand for planes to come in," Francis said.
Francis said there is still a about the lack of skilled trade workers available to work for Premier.
"The issue is being able to ramp up skill sets to meet that demand," the mayor said.
An email sent from CBC News to Premier Aviation inquiring how many people the company employs in Windsor wasn't immediately returned.
The hangar cost taxpayers more than $20 million to build. It can hold two 737 planes and a 747 plane at the same time.
