About Diffusart
More Than Posters on Walls
For more than 35 years, Diffusart has helped organizations connect with audiences through professionally managed poster campaigns and street-level visibility programs across Ottawa-Gatineau.
Unlike simple poster installation services, we provide ongoing monitoring, maintenance, reporting, and visibility management throughout your campaign — ensuring your message stays visible and effective from start to finish.
Based in Ottawa, we serve clients across Canada and the United States — from local arts organizations and community charities to national brands and cross-border campaigns.
