COMMB

COMMB, the Canadian Out-of-Home Marketing and Measurement Bureau, is the national industry association and measurement body for out-of-home advertising in Canada. Based in Toronto and governed by members drawn from across the industry, COMMB provides the audience measurement currency that media owners, agencies and advertisers use to plan and transact campaigns throughout the country. The organization produces standardized audience and impression data for out-of-home placements, applying a methodology that draws on travel and mobility data, circulation information and modeling to estimate who is exposed to advertising across different formats and markets.

Its measurement spans roadside billboards, transit systems, street furniture, place-based venues and digital screens, giving buyers a common basis for comparing and valuing inventory. COMMB delivers this data through planning and analysis tools that support both traditional and digital out-of-home, and it has worked to adapt its measurement to the growth of digital and programmatic trading. Beyond measurement, the bureau serves as a marketing and advocacy organization for the Canadian out-of-home sector, conducting research, promoting best practices and representing the industry's interests.

It also sets standards intended to improve consistency, transparency and confidence in the medium. As a neutral, collectively supported body, COMMB aims to strengthen the case for out-of-home investment by providing trusted, comparable audience metrics and by championing the effectiveness of the channel. Through its combined role in measurement, research and promotion, the organization supports the growth and modernization of out-of-home advertising across the Canadian market and helps align it with wider media practices.
