Brian Ballantyne Specifications (BBS) is a firm of independent construction specifications writers, located just outside Toronto, ON. BBS has been a leader in construction specification writing in Canada for 25 years. With a team of 12 full-time specifications writers, BBS is one of the largest firms of independent specification writers in Canada. We are proud of the growing team of Architects with whom we have the privilege of working.

BBS provides construction specification writing support to Architectural and Interior Design firms, as well as Design/Build teams, Integrated Project Delivery (IPD) teams, and Public-Private Partnership (P3) teams.

While the majority of our clients are located in Toronto, Vancouver, Calgary and Halifax, our projects span throughout North America, from Montreal to North Carolina, from Thunder Bay to Los Angeles, from Dartmouth to Okanagan.  We have succeeded in completing thousands of projects ranging in construction values from $200,000 to $1.5 billion, and in excess of $3 billion annually.







We approach specification writing as an interactive process with our clients, using colour coded draft specifications and spreadsheets to facilitate information exchange and to provide a measure of quality assurance.

Each project starts from a Master Specification to ensure the most up-to-date information is utilized for every project.


The BBS Master Specs are created and managed by BBS. We also subscribe to and use the National Master Specification (NMS) and the AIA MasterSpec.


Ranging from small to large, commercial, educational, industrial and hospitality projects, and interior and exterior projects, the possibilities are endless, and there are no limits, just more experience and expertise to be gained.
