Canada
The Saskatchewan Power Building is a 14-storey office building in Regina, Saskatchewan. Designed by architect Joseph Pettick and completed in 1963, it is Regina's best example of modern architecture. At the time of its completion it was the tallest building in Regina, and would remain so until 1967 when the Avord Tower surpassed it at sixteen stories.
