About Construction Association of Thunder Bay

The Construction Association of Thunder Bay was founded as the Lakehead Builders Exchange in 1949 to foster and advance the interests of those who are directly or indirectly connected with or affected by construction in North-western Ontario.  In 1969, The Lakehead Builders Exchange became the Construction Association of Thunder Bay.

To date, the Association has a membership of 224 firms, an eight to thirteen person Board of Directors, and appropriate staff who work together to publish a daily plans notice, weekly newsletter, yearly magazine (Construction Northwest), a membership directory and buyers guide.

On a day to day basis the Association operates a physical and electronic plans room, BestBidz, as part of Ontario’s network of 11 construction associations and provides affidavit services, sales of CCDC, CCA and other construction documents, full blueprint and specification copying and scanning services, and disseminates information received from affiliated organizations such as CCA, COCA, CECCO, CLRAO, IHSA and regulatory bodies such as WSIB, WSIB and CRA.

The Association facilitates training events that educate its members on the daily operation of their firms. These could be information sessions on current regulations, be it WSIB, MOL, CCRA, procurement to government agencies etc., or training in aspects of, business operation and safety on a jobsite which may include educational or certification requirements. To assist in the safety training of its members, CATB has been a safety group sponsor since 2003. Members benefit from this through rebates on their WSIB premiums.

On the labour relations front, the Association provides a library of local labour rates and collective agreements, along with providing labour relations services to the local General Contractors, Drywall Contractors, Masonry Contractors, Forming and Concrete Placing Contractors and Tiling Contractors.

Throughout the year, the Association facilitates and operates networking events such as golf tournaments, curling bonspiels, a CATB Gala & AGM and other special events to acquaint members with one another and improve their understanding of the industry.
