It was Regina’s first skyscraper at ten storeys high, and the tallest building in Saskatchewan at the time. Real estate developers E.A. McCallum, E. M. McCallum and Walter H.A. Hill began construction of the McCallum-Hill office building in 1912. Designed by Regina architects Storey and Van Egmond, the prime office space faced beautiful Victoria Park and dominated the Regina skyline for years. The McCallum-Hill Building was imploded in six seconds with 200 pounds of explosives in 1982.
