High River resident William Rader was out of his house for almost two months when flood waters swamped most of the town south of Calgary last June.
Rader bought a ticket for the STARS air ambulance fundraising lottery and was one of four grand prize winners.
He says finding out he won a house is surreal and it will take some time to sink in.
The new house — worth $945,000 — is a bit of a drive from High River.
It's located in the central Alberta city of Red Deer.
The lottery draw was originally scheduled to take place on April 17, but STARS officials explained that under the rules of the draw, an early sell-out allowed them to make the draw on Tuesday instead.
