1. One Way, the influencer and video production specialist
One Way is a Montreal based talent management and video production agency that regularly works with Quebec City brands who need a creative partner combining influencer strategy with in house cinematic production. Rather than treating the capital as an afterthought to Montreal, One Way builds campaigns around creators with real Quebec City and provincial reach, paired with a production team that can travel for a shoot or produce remotely. Brands exploring video production services or looking to work with a vetted creator through the talent roster typically start here.
2. Proxima Centauri Publicité
A mid sized shop (11 to 25 people) offering full 360 marketing: brand strategy, creative, SEO and SEM, social media, content and HR marketing. Public profile data shows a 5.0 rating across 54 completed projects, a strong signal for brands that want one team handling strategy through execution.
3. Cobbox Publicité
Cobbox leans into market research, brand and 360 work, creative, and conversion optimization, with a notably high project volume (231 listed projects) and a 4.8 rating. Worth a look for brands that want performance thinking baked into the creative process from the start.
4. Novatize Publicité
A larger team (51 to 100 people) focused on composable commerce and eCommerce brand building alongside creative and 360 marketing, carrying a 4.9 rating. A fit for retail and DTC brands based in or around the capital that need commerce infrastructure and brand work from the same partner.
5. Déry, Résultats Marketing
Operating for more than 40 years, Déry covers print, experiential marketing, brand work, SEO and SEM, social and content, with a 5.0 rating. For brands that value longevity and a long local track record over a flashy portfolio, this is one of the capital's most established names.
6. Turbulences
Turbulences specializes in public relations, crisis management, TV, radio and print advertising, events, influencer campaigns and stunt marketing. A strong choice for brands that need PR muscle alongside creative, particularly around a product launch or a reputational moment.
7. Agence Edgar
A boutique shop (2 to 10 people) focused on brand building, market research, SEO, social media and content, holding a 5.0 rating. A fit for smaller or mid sized brands that want a close, hands on relationship with their agency team.
8. Accélérer Publicité
Accélérer focuses on reputation management, investor relations, print and experiential marketing, also carrying a 5.0 rating. Relevant for organizations, public or private, that need communications discipline as much as creative output.
9. Kairos MerakIT
Kairos MerakIT focuses its PR, events, and traditional and influencer advertising work specifically on the technology sector, a useful specialization for Quebec City's growing IT and software scene.
10. Les Mauvais Garçons
A mid sized team (11 to 25 people) doing brand and 360 creative work with a name that signals exactly the kind of irreverent energy they bring to a brief. A good option for a brand looking to stand out rather than blend in with the capital's more traditional agency names.
How to choose between them
Start by narrowing on what you actually need this quarter rather than the agency with the longest service list. A launch that needs press coverage points toward a PR focused shop like Turbulences or Kairos MerakIT. A retail brand building out an online store leans toward Novatize. A brand that needs creators and video content working together under one roof is the exact gap One Way is built to fill, including for teams based outside Montreal, as covered in our piece on why brands keep finding their creative partner outside their own city.
