Why first-party data is becoming the most important asset in your media plan.
The promise of digital advertising has always been precision. But third-party cookies are less reliable every year, big platforms offer reach without transparency, and most brands can't easily use their own customer data without raising privacy concerns.
Advertisers keep hitting the same wall: Am I reaching the right people? Can I prove it worked? And can I do this while protecting my customers’ privacy?
SJC’s Audience+ was built to answer those questions.
What Is SJC Audience+?
SJC Media publishes some of Canada’s most-read brands: Toronto Life, Maclean’s, FASHION, Chatelaine and Today’s Parent. SJC Audience+ pairs that trusted readership with Optable’s privacy-safe data technology, giving advertisers a smarter way to plan, target, activate and measure campaigns across SJC’s premium digital inventory.
Audience+ helps advertisers reach more relevant audiences using SJC Media’s first-party reader data and clean room collaboration.
“The opportunity here is growth,” says Vlad Stesin, co-founder & CEO of Optable. “Advertisers connect their data to SJC to find and win customers they were missing, on premium inventory they can trust.”
Two Ways It Works
1. Custom Audience Segments Built on Real Reader Data
Rather than relying on guesswork or outdated demographic models, advertisers can tap into what SJC’s millions of monthly readers actually engage with. Available segments include:
- Arts & Culture
- Food & Drink
- Fashion & Style
- Health & Lifestyle
- Business & Finance
- Home & Garden
- Real Estate
These audiences are built from real engagement signals—what people read, click and return to—delivering stronger contextual alignment and cleaner data than typical third-party segments.
2. Direct Data Collaboration Through a Secure Clean Room
A clean room lets your brand and SJC compare data and draw insights without either side ever seeing the other’s raw customer information. Your data stays yours. Ours stays ours.
Here’s the process:
Plan. Match your customer data against SJC’s readership to find overlap before committing a budget.
Activate. Run campaigns using audience targeting informed by first-party insights and clean room analysis, via direct partnerships or programmatic channels.
Measure. Close the loop: understand which audiences converted and plan smarter next time.
“Canadian advertisers want quality data from a source they trust, without sacrificing flexibility in how they buy,” says Drew Thachuk, director of programmatic and data solutions, SJC Media. “SJC Audience+ delivers exactly that. From our established segment catalogue to bespoke solutions for select advertising partners, everything is designed around privacy and platform interoperability, so agencies and advertisers retain full flexibility and control over how they activate.”
Why First-Party Data Matters More Than Ever
The signal loss is already here. Privacy legislation in Quebec and across Canada is evolving, consumers are more aware of data use, and many familiar targeting tools are becoming unreliable.
AI is also reshaping how campaigns are planned and optimized—but as Geoffrey Bernard of La Presse said at Optable Connect 2026: “AI is only as valuable as the data it’s built on.” Fragmented, low-quality data produces weak results regardless of the technology on top of it.
SJC Audience+ is built on clean, consented, first-party reader relationships, giving advertisers a stronger foundation at every stage of the campaign.
Common Questions We Hear From Advertisers
What is a data clean room?
A secure environment where your brand and SJC can compare audience data and generate insights without exchanging raw customer information. What you get are aggregate insights for better targeting, overlap analysis and measurement, with privacy compliance built in.
We already have our own CRM data. How does this help us use it better?
Your CRM only tells you about people you already know. The clean room lets you match that data against SJC’s readership to find new high-value audiences who look like your best customers, extending your reach without handing your data to anyone.
Do advertisers need their own first-party data to use SJC Audience+?
No. You can use SJC’s audience segments on their own, or combine your customer data for more advanced matching. The platform works for brands at any stage of data maturity.
How is this different from just buying a programmatic audience segment?
Traditional programmatic segments are built from third-party data aggregated across the open web. Audience+ is built on direct engagement signals from SJC’s own readers: cleaner signal, stronger context, real audience relationships.
What types of campaigns work best with SJC Audience+?
Audience+ supports brand awareness, consideration, acquisition and retargeting. It’s especially strong for advertisers looking to reach engaged Canadians, activate first-party data safely, improve contextual alignment or measure performance more effectively.
How does SJC Audience+ support privacy compliance?
The clean room architecture means no raw user-level data is ever shared between parties. The platform is built to support Canadian privacy standards, including Quebec’s Law 25.
