Our Story


Our Philosophy 

We are dedicated to a new level of excellence in customer service. Our commitment is what fuels our growth. By partnering with our customers, employees and suppliers, we provide innovative and effective solutions for the building industry. 

We are a contractor lumber yard focusing one hundred percent on the builder, providing superior service for our customers. We have been here for the contractor since 1985. Our clientele consists of some of the industry's finest home builders, multi-family contractors, general contractors, as well as commercial, industrial and institutional accounts. Whether you are requiring lumber, engineered I-joists, trusses or interior finishing products, we stock it all! 

Our trading area ranges throughout Alberta into the Yukon, Territories, and even Alaska. Our fleet of delivery trucks are always on the move throughout the City of Edmonton and the surrounding area. Long hauls have taken our products from the west coast east through to Sault Ste Marie, from the US border north to Inuvik. No matter where the project is, we can deliver it all!

The Mission Difference 

Contractors, we understand that it's your reputation on the line. You need the highest quality products, top-notch customer service and the confidence to know that your project will come in on time and within budget. Our fully stocked yard means you get the premium supplies you need, when you need them, delivered where and when you want them. That’s the Mission difference. 

While we’re large, we’re 100% Canadian, and locally owned and operated. We know what products to recommend. We have long-established relationships with the best contractors in the business and the best suppliers in the business. No one surpasses our knowledge of the industry. Ask us for what you need, and we'll get it! That is our promise to you!

Five Generations of Expertise

There have been five generations of Clements in the industry. In 1985 with big dreams and a strong work ethic, Karen and Tom Clement purchased Mission Building Supply. Their philosophy was then and still is today, to acknowledge every customer regardless of the size of their project. In 2010, Karen Clement was Western Retail Lumber Association's first woman President in its 120 year history! Tom Clement served on the board of Castle Building Centre Group for six years, and was Chairman of the Board for two years. Today their son, Don Clement, is the Assistant Manager of Mission Building Supplies.

Giving Back

Supporting and giving back to the communities that we help build is a passion for Mission Building Supplies. Don Clement can seen helping out the kids at a bottle drive to raise funds for a playground in Lake Hudson or taking a swim in the dunk tank at the Oxford playground grand opening. Since 2009 we've been a proud supporter of Stars Air Ambulance by donating all the lumber and materials for the building of the STARS annual lottery home.
