Hospital Lottery Homes - Question

New to the forum, some good infomation.

I have a question ?? I buy the hospital lottery tickets for Princess Margaret Hospital in the hope of winning a house. I spend $500.00 each time, never won but it is a good cause. My question is does the hospital pay for house to be built, is it donated bi a builder or does the Ontario Government pay for the house to be built.
Thanks

Dan

No. All prizes are purchased by the Foundation using the tender process.
