Canadian Out-of-Home Measurement Bureau (COMB)

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 over 70,000 OOH advertising faces and screens in over 280 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.
