At 9 p.m. Friday, it shut down for good.
West End YMCA officials decided in January to close the Ontario-Montclair YMCA facility at 215 W. C St. due to its financial struggles.
For many, like Charles Cole of Ontario, the facility served as a home away from home.
"All the people here are family and it's always a family atmosphere," said Cole, 55, as he pumped away Friday on an elliptical machine.
The building opened in 1914 at 205 W. C St. and contained the first two bowling alleys in the area. Membership and activities vastly outgrew the facility.
By 1948, the building was torn down and rebuilt at 215 W. C St.
However, in the past decade, officials have had to deal with a tough economy and declining membership while maintenance for the old building continued to be a burden.
About 40 employees gathered Thursday for a farewell banquet to reminisce and remember better times.
Despite its closure, the YMCA will continue to offer child-care programs at two Ontario elementary schools as well as its Silver Stars Senior Transportation Program.
Churches using the Y facility can continue to conduct services for six months, but the Kiwanis and Lions clubs will have to have their final meetings by March 31.
The facility was part of the West End YMCA, which serves Chino, Chino Hills, Ontario, Montclair, Upland, Rancho Cucamonga and Fontana. West End YMCA still has facilities in Chino, Upland and Rancho Cucamonga.
For more than 20 years, Cole has been attending the Ontario YMCA. He said he practically raised his two sons on its basketball courts.
On Monday, Cole said he'll attend the Upland-based YMCA to "give them a shot."
"I hate to see them closing down," he said.
"This Y provided the community with family values and people working together."
