Calgary-Hays is a provincial electoral district mandated to return one member to the Legislative Assembly of Alberta, Canada using the first past the post method of voting.

The 2010 boundary redistribution split the riding in half to form most of Calgary-South East due to significant growth of new communities in the southeast quadrant of Calgary.

He won a higher popular vote but his percentage of victory dropped as the Liberal and Wildrose Alliance candidates made gains.

Johnston announced his retirement as incumbent after being defeated twice for the Progressive Conservative nomination in Calgary-Hays and in the new electoral district of Calgary-South East.

In 2012, PC Candidate Ric McIver defeated Wayne Anderson, contender for the Wild Rose Party, to become the second representative for the Hays district since its creation.
