About Us
More Than Posters on Walls
Our Story
Ottawa's Out-of-Home Advertising Experts
Founded in Ottawa in 1988, Diffusart Media has been helping organizations attract attention and build awareness through professional street-level advertising for more than three decades.
From arts and cultural organizations to festivals, charities, community initiatives, sporting events and commercial brands, we design and manage campaigns that place our clients where people actually live, work and move throughout their day.
Our work extends across Ottawa-Gatineau and the National Capital Region, with the ability to coordinate regional and national campaigns when broader coverage is required.
Unlike simple poster installation services, our involvement does not end when the materials are posted. Campaigns are regularly monitored in the field, damaged or missing materials are replaced when necessary, and visibility conditions are documented throughout the campaign to help ensure clients receive the exposure they expect.

How We Work
What Makes Us Different
Daily Field Inspections
Unlike one-time install services, we inspect our full network daily — and multiple times per day during peak periods. Every poster you see on the streets of Ottawa or Gatineau is part of our network, and we make sure it stays that way.
Active Visibility Maintenance
We don't just post and move on. Damaged or covered materials are replaced promptly. If something gets posted over your work, we fix it. Your campaign stays visible for its entire duration — not just day one.
Local Expertise
35+ years of on-the-ground work in Ottawa-Gatineau means we know exactly where your audience is — which streets, which neighbourhoods, which boards deliver real visibility.
Bilingual Service
The National Capital Region is bilingual, and so are we. We serve clients in English and French, and understand the cultural landscape of both communities.
