Jerry Mainil received his welding pressure ticket, but had his first experience welding in the backyard of his parents’ Weyburn home in the 1950s. In 1961, Jerry incorporated his business and moved the business into where Jerry Mainil Limited is still located. He hired four men to keep with the growth in the energy industry as well later expanding into the agricultural and civil industires. 

Jerry’s sons; Dennis and Dale joined him in the family business, going on to purchase it in the early 1990s along with their brother-in-law, Calvin Tracey. Over time, the business has continued to grow from four original employees to currently employing 80-110 men along with a vast fleet of equipment. Dennis, Dale and Calvin continue to operate Jerry Mainil Limited with the same honesty, integrity, and knowledge the company was built on over 60 years ago.

Jerry Mainil Limited prides itself on its qualified, experience personnel who have proven skills and abilities to handle any type of construction project, solving complex construction problems with safe and cost-effective solutions.
