The biggest chance for a return of major professional hockey came in 1982. Bill Hunter, a local sports promoter, attempted to purchase the St. Louis Blues of the NHL and move it to Saskatoon, but the move was prevented by the league. This was due to Saskatchewan's and especially Saskatoon's small size in relation to both St. Louis and the other cities in the NHL at the time. However, it did cause the building of the Credit Union Centre, on the city's northern edge. Prior to hosting the 2010 World Junior Hockey tournament, the arena underwent a major expansion which increased seating capacity to approximately 15,200 and also created several new box suites.
