Cairns Oneil, a leading Canadian media agency, has been awarded the distinguished Global 100 — Best Marketing & Advertising Firm of the Year (Canada) 2025. This honor distinguishes the agency as a standard-bearer for innovation, transparency, and excellence in the Canadian marketing sector.

Founded on the principle that agencies should work as true agents for their clients, Cairns Oneil has rapidly established a reputation for crafting bespoke strategies that leverage the best technology and media—earning repeat business and trust from brands that prioritize outcomes and transparency.

Transforming the Canadian Media Agency Landscape

Cairns Oneil is widely recognized as a transformative force in the industry, credited with bridging the gap between large global networks and smaller boutique firms through a transparent, agnostic, and senior-led approach. The firm stands out for its refusal to engage in principal-based media buying practices, instead focusing exclusively on delivering outcomes and exposing all fees and costs to clients without locked-in media positions or media reselling.

When we talk to clients about not having principal-based media buying, we realize that we may be the only real media agency of scale that still acts as a true agent,” the firm notes about their unique positioning.

Values That Drive Success

Cairns Oneil’s rapid growth—doubling in size over just four years—is attributed to core values of transparency, agnosticism, and integrity. These values are reflected in every aspect of the business model:

  • Transparency: Full disclosure of all costs and fees to clients.
  • Agnostic Approach: No locked-in media contracts; freedom to use the right platforms for each client.
  • Integrity: Client outcomes take priority over agency commissions.

This approach has led an increasing number of marketers to switch to Cairns Oneil, seeking a “new way to use media to drive their business forward.”
