The donation by Dan and Sarah Hamhuis will help build the new 73-room Ronald McDonald House BC on the grounds of BC Children's Hospital.
Canucks' defenceman Dan Hamuis says he and his wife began working with the organization while he was playing hockey in Nashville.
A native of Smithers, B.C., he says he witnessed first hand how Ronald McDonald House BC has helped out his friends.
Construction on the house is scheduled to begin this fall, with a completion date set for January 2014.
Ronald McDonald House BC thanked the Hamhuis family for the contribution and noted the facility will be the organization's second largest house in Canada.
