Yahoo DSP Integrates Moneris Retail Data, Bringing Real-World Purchase Behaviour Into Canadian Programmatic

Programmatic advertising in Canada just moved closer to the point of sale.

Yahoo and Datadesk have announced a new partnership that integrates Moneris retail transaction data directly into Yahoo DSP. For Canadian advertisers, this is the first time large-scale, real-world purchase behaviour data from one of the country’s largest payment processors can be planned and activated programmatically within Yahoo’s buying platform.

Moneris processes roughly 40% of all retail transactions in Canada across more than 325,000 merchant locations. Through Datadesk, Moneris’ exclusive data provider, that transaction intelligence is now accessible inside Yahoo DSP. This gives advertisers the ability to build and activate audience segments based on actual spending behaviour rather than proxies such as browsing history or search intent.

Why This Matters

Retail media has been accelerating globally, but in Canada, access to scaled, privacy-compliant transaction data has been relatively limited.

This integration begins to change that.

In addition to its physical retail footprint, Moneris powers payment gateways for thousands of Canadian ecommerce sites. That means Yahoo DSP buyers can layer:

• In-store transaction data
• Online purchase behaviour
• Yahoo’s own commerce and audience signals

The result is cross-funnel targeting aligned to how Canadians actually spend across 15 million households and 850,000 postal codes.

Instead of optimizing only for impressions and clicks, advertisers can plan against aggregated purchase behaviour across verticals including grocery, QSR, automotive, travel, and retail. Media planning moves closer to real revenue outcomes.

Privacy by Design

The integration has been structured around Canadian and global privacy standards. All segments are aggregated and anonymized, with no individual-level reporting and no attribution tied to specific transactions.

The data meets Canadian privacy requirements as well as GDPR and CCPA standards.

In a market where data regulation and signal loss continue to reshape targeting strategies, scaled transaction data that is privacy-safe by design offers an alternative to cookie-dependent approaches.

A Broader Shift in Canadian Programmatic

Vince Simone, Head of DSP at Yahoo Canada, says the partnership strengthens Yahoo DSP’s commerce capabilities in Canada by enabling advertisers to target based on how consumers actually spend, not just how they browse.

Lyle Wagner, Founder of Datadesk.io, frames the opportunity clearly. Digital media has historically optimized toward clicks and impressions, while revenue happens at the point of sale. Integrating Moneris transaction data into Yahoo DSP aims to narrow that gap between exposure and real-world spending.

Strategically, the announcement reflects a broader evolution underway in Canadian programmatic:

• Media planning increasingly anchored to commerce data
• Convergence of online and offline purchase signals
• Retail payment data entering mainstream DSP environments
• Growing demand for outcome-focused audience strategies

As retail media networks expand and commerce data becomes more central to media buying, integrations like this suggest Canada’s ecosystem is moving beyond traditional demographic and interest-based targeting.

What This Unlocks for 2026

For advertisers, the implications heading into 2026 are significant:

• Smarter vertical-specific targeting based on verified spending behaviour
• Improved prospecting using real purchase signals
• Stronger audience modeling across online and offline environments
• More accountable programmatic investment tied to real commerce activity

Whether this becomes a foundational shift in Canadian programmatic or remains a competitive differentiator for Yahoo DSP will depend on adoption. Either way, it signals that transaction data is becoming a core input into media decision-making.

For marketers focused on retail media, commerce intelligence, and performance-based planning, this partnership is worth watching closely.
