The Canadian Out-of-Home Measurement Bureau

The Canadian Out-of-Home Measurement Bureau (COMB) 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.

COMB’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 COMB for measurement of its Canadian out-of-home products. COMB 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.
