C.M. Fines Building, High-rise office building in Regina, Canada

The C.M. Fines Building is a 20-storey office tower at 2260 11th Avenue in Regina, Saskatchewan, completed in 1979 and designed by Joseph Pettick. Its energy-efficient reflective windows contain gold dust, which gives the facade its colour. The tower houses the corporate offices of Saskatchewan Government Insurance (SGI).

Built in 1979, the structure held the title of Regina's tallest building until 1988, marking a period of urban growth. This nine-year prominence reflected the region's economic aspirations during that era.

The tower is named after Clarence Melvin Fines, Saskatchewan's provincial finance minister in the 1940s and 1950s, who played a major role in establishing Saskatchewan Government Insurance. SGI's corporate offices occupy the building, so the name ties the structure directly to the Crown corporation it houses.

The C.M. Fines Building stands at 2260 11th Avenue in Regina, at the coordinates 50.45056, -104.61333. It is an office tower housing SGI's corporate offices, so interior access is for staff and visitors with business there rather than general sightseeing. The gold-tinted reflective windows are best seen from the street outside.

In 2004, the building underwent a major renovation to repair water damage affecting its post-tension cable systems, demonstrating the ongoing care needed for such structures. This investment secured the long-term durability of the landmark.
