Independent. Senior.
Connected.
Founders · Built in Montreal
MUM is an independent media buying agency built by Monteith and Usheroff — operators with decades of experience in the Canadian media industry and direct, long-standing relationships with the country's leading media owners, broadcasters and publishers.
Our roots are in Montreal hospitality, where attention drives revenue and there's no hiding behind a slide deck. That operator instinct is what we bring to every campaign — paired with the buying expertise and negotiated pricing power most brands simply can't replicate on their own.
We're not part of a holding company. We're not a media owner trying to sell our own inventory. We're independent buyers, on your side, with the relationships to back it up.
Agile enough for local. Sophisticated enough for national.
"We don't just buy media — we know where it lives, who runs it, and what it should cost."
This is where we flourish.
Becoming a company's Agency of Record — and managing their marketing needs across the board — is where MUM does its best work.
We don't just run one-off campaigns. We become the marketing partner that owns the full picture: planning, buying, negotiating, launching and reporting across every channel. When we're your AOR, there's no fragmentation, no competing vendors, no gaps in accountability. Just one senior team that knows your business, your audience, and your goals inside out.
One relationship. Every channel. Total ownership.
From local rooms to national rollouts.
Agencies
Creative shops and full-service agencies who need white-label buying support, better rates, or a media partner that won't compete with them.
National & Regional Brands
Enterprise brands, franchises, automotive groups and developers running multi-market campaigns who want senior buyers, not account managers.
Local Operators
Restaurants, venues, retailers and SMEs spending real money on media without senior buying expertise behind the plan.
Sound like a fit?
No pitch decks, no theatre — just a real conversation about your next campaign and the rates we think we can secure for it.
