Third-party cookies are no longer the centre of the remarketing universe. Even as Chrome’s plans have shifted, privacy features across major browsers and mobile platforms have already changed how ads find people. In Canada, that means retargeting has to evolve from a user ID mindset to a context and creative mindset. Remarketing is not gone. It is different. The teams that adapt will keep their performance while gaining trust.

The End of Third-Party Cookies and What It Means for Retargeting

For years, classic remarketing relied on third-party cookies to recognize a visitor and show tailored ads as they moved around the web. That method has been weakened by privacy controls in Safari and Firefox, tighter rules on mobile, and steady changes to how Chrome manages identity and measurement.

In mid-2025, the UK regulator signalled that Google’s earlier cookie removal commitments were no longer needed, reflecting a step from a single deprecation deadline. What did not change is the direction of travel. Privacy-focused APIs and user choice are here to stay, which means brands still need a plan that works without cross-site IDs.

The practical takeaway is simple. Assume less user-level tracking and build remarketing that survives with context, consented data, and strong creativity.

Contextual Targeting as the New Remarketing Foundation

Contextual is the practice of aligning your ad with the meaning of the page, the video, or the moment. Instead of following an individual across sites, you choose placements and topics that match buyer intent. A person reading about home renovation is a good candidate for a contractor ad. A viewer watching a demo-style video is primed for a free trial message. Modern platforms offer topic and content signals that get you close to the right audience without storing personal identifiers.

How to use it well

• Map placements to the questions buyers ask at each stage of the journey
• Pair topics with a creative built for that context, not a generic ad
• Protect the brand with suitability settings so your ads avoid risky content

Contextual works best when your website experience is ready to convert that interest. If you need support tightening up page speed, structure, and conversion paths, our SEO and Paid Media teams can align targeting with on-site performance.

Creative as a Retargeting Signal

When user IDs fade, your message carries more weight. Creative becomes the signal that moves someone from interest to action. You can segment by funnel stage without tracking a person across sites. Speak to behaviours you observe on your own properties and to the context of the placement.

Practical moves

• Build a small family of ads for each theme, from reminder to offer to proof
• Use a creative that acknowledges what the person is likely doing in that moment, such as reading a guide or watching a how-to clip.
• Keep brand elements consistent so recognition compounds across channels
• Test hooks, first lines, and visuals in short weekly sprints and retire losers early

Using First-Party Data to Rebuild Remarketing

First-party data remains powerful when it is consented to and organized. Email lists, site behaviour, and CRM segments let you run respectful audience programs that still feel relevant. The key is transparency and a clear value exchange. People share data when they understand what they will receive in return.

What to collect and how to use it

• Capture email with useful lead magnets, trial offers, or notifications people actually want
• Build segments based on actions on your site and in your product, then sync them to ad platforms in a privacy-aware way.
• Set frequency caps and lifespans so your ads do not overstay their welcome.

Regularly clean lists for quality and compliance

PIPEDA requires meaningful consent for the collection, use, and disclosure of personal information. It also expects that the purposes are clear and appropriate. Align your consent and audience practices with that standard so that trust and performance move in tandem.

Platforms Leading Post Cookie Strategies

Ad platforms are shipping features that lean on modeled conversions, aggregated signals, and context rather than third-party identifiers. You will see more topic-based targeting, improved interest signals that avoid sharing site lists, and better integration with your CRM or e-commerce platform. Expect continued updates to server-side measurement, event quality checks, and brand safety controls.

What to watch

• High-quality conversions from your own site and app with clear consent and clean event names
• Modeled reporting that fills gaps when browser signals are limited
• Topic and content controls that map to your buyer research

Measurement and Attribution Without Cookies

You can still know what is working. The mix just changes. Click trails, modeled conversions, and lift tests replace exact user paths. Server-side event forwarding improves signal quality to analytics and ad platforms when front-end tags are blocked. Funnel views focus on clusters instead of individuals. The question shifts from who saw which ad to which combination of context, creative, and offer produces profitable outcomes.

What to track

• Conversions and payback by channel and campaign group
• Assisted in the impact of content and brand placements on final actions
• Landing page speed and clarity, since performance influences both ads and search

Creative Testing and Iteration Are Your New Superpowers

The fastest gains often come from better creative matches to better context. Run nimble tests, not bloated experiments. Aim for clear lessons each week.

A simple cadence

• Pick one theme and ship three variants across a small set of contexts
• Hold the budget steady for a full learning phase to avoid false negatives
• Keep a library of proven hooks, lines, and visuals so you can remix quickly
• Use short-form video and creator-style content where your audience already spends time

Canadian Privacy Considerations

Treat privacy as part of your brand. Explain what you collect and why. Make opt-in clear. Honor opt out quickly. If you sell in Quebec or handle sensitive categories, review local requirements with care.

Nationally, PIPEDA sets the bar for meaningful consent and appropriate purposes, and the Office of the Privacy Commissioner continues to update its guidance. Build remarketing plans that make sense if a customer were to read them from start to finish.

Quick Action Plan for Canadian Brands in 2025

Audit your remarketing
List every audience and tag. Mark, which ones depend on third-party cookies and which ones rely on your own data or on context?

Stand up a contextual test

Choose one high-value theme. Pair two or three creative angles with topic and placement controls. Measure against a clean conversion.

Invest in first-party data.

Tighten consent flows. Improve lead capture. Sync clean segments to ad platforms and set thoughtful frequency and durations.

Upgrade measurement

Use server-side event forwarding where it makes sense. Simplify dashboards so decisions are obvious. Align reporting windows across platforms to reduce confusion.

Tighten the website

Faster pages and clearer offers lift everything. Your remarketing pays off when the landing path removes friction.

Conclusion: Remarketing Is Not Dead. It Is Smarter Now.

The next era of remarketing is less about following people and more about showing up at the right moment with the right message. Context, creative, and consented data form a durable engine that will outlast policy shifts. As cookie reliance fades, your brand gets a chance to compete on clarity and usefulness.
