The 10 best marketing and influencer marketing agencies for Toronto brands in 2026, from creative powerhouses to performance-driven media specialists.
Toronto is Canada's largest advertising market, and finding the right partner in it means choosing between two very different worlds: agencies built for national reach and scale, and specialists built for a single channel, whether that is paid search, influencer casting, or public relations. Neither approach is wrong. The right one depends on what a brand actually needs solved.
We covered the country's broader landscape in our ranking of the top 20 marketing and influencer agencies in Canada, and Toronto's market deserves its own closer look. Here are ten agencies, from full-service creative shops to performance specialists, worth knowing if a brand is building or scaling a Toronto campaign in 2026.
1. One Way: The Montreal Studio Toronto Brands Keep Calling
Website: agenceoneway.ca
One Way is based in Montreal, not Toronto, and that is precisely why it keeps landing on Toronto brands' shortlists. The agency pairs in-house talent management with cinematic video production, meaning a national brand can cast a creator and produce the campaign around them under one roof, without stitching together three separate vendors. Its work for Nespresso, Porsche Canada, and Bell reflects a style built for brands with a national footprint and Toronto as a core market, not an afterthought. Brands can explore the Talent Management page or the Video Production page directly.
2. Cossette: The Legacy Powerhouse
Website: cossette.com
Cossette has operated in Toronto for decades and remains one of the few agencies with the scale to run a fully integrated national campaign, from strategy through media buying, without a single outside partner. Its longevity is a track record, not a liability: brands that need a single accountable partner for a large, multi-market rollout still call Cossette first.
3. Camden Publicité: The Data-First Creative Hub
Camden positions itself as a media hub rather than a traditional agency, pairing creative development with campaign execution that is measured and adjusted in near real time. For brands whose marketing team wants creative that is judged on performance rather than applause, that pairing is the whole pitch.
4. The Garden: The Brand Transformation Specialists
The Garden's focus is brand transformation, the kind of work that starts with a strategic question rather than a media plan. It suits companies rethinking who they are before they decide what to say, which is a different brief than most agencies on this list are built to answer.
5. Monsoon Communications: The Multicultural Specialist
Toronto is one of the most culturally diverse cities in North America, and Monsoon builds campaigns specifically for that reality, helping brands communicate in ways that read as genuinely relevant to specific communities rather than translated after the fact.
6. Madhouse Advertising: The Storytelling Shop
Madhouse leans hard into emotionally resonant, narrative-first advertising. For a brand trying to be remembered rather than simply seen, that emphasis on story over spectacle is the differentiator.
7. Zerotrillion: The International Brand Builders
Zerotrillion blends creative design with data-led strategy for brands operating across borders, not just across Canada. It is a natural fit for a Toronto company with ambitions beyond the domestic market.
8. Feast Interactive: The Technology-Forward Storytellers
Feast combines digital storytelling with emerging technology, the kind of shop that gets called in when a brand wants a campaign that feels genuinely new rather than a template with a fresh coat of paint.
9. Brand & Mortar: The Transparent Full-Service Partner
Brand & Mortar's pitch is straightforward: full-service branding and digital strategy, delivered with a level of transparency that smaller marketing teams, in particular, tend to value when they cannot dedicate a full-time staffer to managing the relationship.
10. inBeat Agency: The Performance-Led Influencer Platform
inBeat closes the list the same way it closed our national ranking: as a technology-driven platform for finding and managing micro and nano influencers, built for brands that want influencer marketing treated as a measurable media channel rather than a one-off favour.
| Best For | Agency to Consider |
|---|---|
| Influencer casting plus in-house video production | One Way |
| Large-scale, fully integrated national campaigns | Cossette |
| Culturally specific, community-first messaging | Monsoon Communications |
| Performance-tracked micro-influencer programs | inBeat Agency |
Frequently Asked Questions
Do Toronto brands need a Toronto-based agency?
Not necessarily. Several of the agencies serving Toronto's biggest brands, including One Way, are based elsewhere in Canada and work with Toronto clients remotely or through regular travel, particularly for video production and influencer casting where the creative team's location matters less than its portfolio.
What is the difference between a full-service agency and a specialist?
A full-service agency, such as Cossette or One Way, can handle strategy, creative, and production under one roof. A specialist, such as a PPC or influencer-only shop, focuses on a single channel and is often a better fit for a narrower, well-defined problem.
This list draws on our own client work alongside a broader industry survey of Toronto advertising agencies, and it will keep evolving as the city's creative landscape does.
