Leon asked city staff during Tuesday's council meeting to prepare a study regarding the potential future use of the now-defunct facility.
"I am not happy with the YMCA and the way the city of Ontario was treated," said Leon, adding he had no idea of the organization's financial situation until he read it in the newspaper.
Citing declining membership and sluggish financials, the organization announced in early January that it would shut the doors of its Ontario site last Friday.
Officials with the YMCA have said the facility was operating with a $140,000 deficit and had lost more than 150 members in the past three years. The West End YMCA also oversees other Y programs at branches in Chino, Upland and Rancho Cucamonga.
But Leon faults those deficiencies on changes that occurred within the organization in 2010. That year the YMCA decided to reorganize its structure and eliminated executive positions in Ontario and Rancho Cucamonga. The change in administration resulted in the entire board of directors to be dismissed.
Since then, Leon said, there has been a lack of support from the new administration for the Ontario facility. Most notably, the lack of fundraising efforts, he said.
"I would like to study what it would take to take over the facility," Leon said. "We don't have another facility for youth in the downtown."
