Fredericton's Trusted Building Supply Partner

Topmar Building Supplies Ltd. is a private, family-owned firm located on the north side of Fredericton, New Brunswick. We've proudly served our local community for more than 40 years.

More than just lumber, Topmar Building Supplies continues to be Fredericton's trusted building supply partner, serving contractors and homeowners with quality products that help them turn their project plans into reality.

Our history

In 1964, John Mahar & Calvin Thompson formed a partnership known as Thompson & Mahar, a construction company where three homes were constructed that year.

In early 1965, the partnership was incorporated under the name of Topmar Housing & Construction comprising of three letters from Mr. Thompson's name and three from Mr. Mahar's name.

They expanded into the commercial field with a steady growth.  In 1968, they moved to a one-acre site in the industrial park.  In 1970, Topmar Building Supplies was incorporated.  With consistent growth and performance, Topmar Building Supplies spread out with many contracts around the province of New Brunswick.  In 1976, they outgrew their old location and moved into a large new building consisting of a showroom, warehouse, service area, and offices with the intention of meeting the local builders' requirements with materials and services at fair trade prices.

As a family business, Topmar Building Supplies continued to grow in service and dedication to Fredericton and the surrounding area, until they moved location to a bigger site in North Devon, in the year 2000.  Now on 140 Clark Street, Topmar Building Supplies serves their customers from a 20,000 sq. ft. store, including a drive through lumber yard for many building products, delivery service, tool & equipment rental, screen repair, key cutting, and free estimates so that our customers can begin and complete their projects all from one location.
