WE Care For Kids is committing $400,000 towards the city's new Ronald McDonald House inside Windsor Regional Hospital.
This is the largest single donation of the $1.4-million project.
Executive Director of the Ronald McDonald Charities southwestern Ontario Margaret Anderson says she's thrilled.
"The Windsor community has been phenomenal and I don't think we were ever expecting these sizes of gifts to come along," she says. "It made the whole project speed up because we were able to secure the funding and be able to move along very, very quickly."
Private donours have come forward with $270,000 and officials are asking for the public's help to raise the rest. Stephanie and Barry Zekelman, David and Camille Cecchin and Windsor Textiles Limited all contributed.
Fundraising head Celina Ussoletti says the Bear Hug Pin Campaign will help raise the remaining $130,000.
"So what you can do with this is purchase a pin for $20 and the money donated will be to the Ronald McDonald House, but the actual pin will be given, your choice, to someone who has made a difference in your life," says Ussoletti.
Windsor's Ronald McDonald House opens May 6 at Met Campus on the third floor. Right now crews are putting the final touches on the "home-like cottage-chic" space.
Public open houses are running May 7 from 10am-4pm and May 8 from 12pm-4pm.
