The Canadian Out-of-Home Marketing and Measurement Bureau

The Canadian Out-of-Home Marketing and Measurement Bureau (COMMB) sets the industry standard for measurement of OOH advertising audiences across Canada, providing a consistent, common way to evaluate OOH media.

It publishes circulation and planning data for close to 80,000 OOH advertising faces and screens in over 250 markets.

COMMB’s Research Committee - an important “policing body” of research and media experts - ensures that all methodologies are thoroughly analysed for integrity, precision and the highest standards of research practice.

Lamar relies on COMMB for measurement of its Canadian out-of-home products. COMMB holds its members to the highest standards of performance by conducting random audits of OOH postings – unannounced, anytime, at any location.

Audit scores are published twice per year.
