Discovering Mainprize Regional Park

Mainprize Regional Park, which sits on the northwest shoreline of Rafferty Reservoir amidst Saskatchewan's oil patch, was named in honour of the late Doctor William Graham Mainprize. Visitors often describe the park as an oasis amidst the flat grainfields, rocky grasslands, and numerous pump jacks, appearing as if it were dropped from the sky.

Doctor William Graham Mainprize

Dr. William Mainprize dutifully served the Midale area for 54 years. The man was known for his resourcefulness, always finding a solution where others found only obstacles.

Dr. Mainprize was a brilliant doctor and engineer who graduated as the youngest person ever from the University of Toronto's medical program. Despite his success, he chose to settle in Midale, where he served the town and surrounding areas for over 50 years. Known affectionately as "Doc" by generations of locals, he was a dedicated and pioneering doctor who went above and beyond for his patients, often traveling long hours by horse or sleigh to attend to their needs.


In addition to his medical duties, Doc inspired and encouraged the community to develop and become better. As a testament

to his lifetime of selfless service,

the town of Midale and surrounding areas named a park after him in 1959.
