Agentic E-Commerce: How It Works and Where Canada Stands

Agentic e-commerce refers to purchases an artificial intelligence agent makes on behalf of a consumer, based on an authorization that consumer has granted it. This is no longer science fiction: ChatGPT, Google, Perplexity, and Shopify each rolled out their own version in 2025 and 2026, with very mixed results. For a Quebec SMB selling online, understanding this shift is becoming just as important as understanding the arrival of mobile or social media once was.

You describe what you want to an assistant like ChatGPT or Gemini: the agent searches, compares, and prepares the purchase, but you’re always the one confirming the transaction, whether at the moment of purchase or through an authorization set up in advance. It’s not a tidal wave yet, but it’s moving fast, and Canada is only just starting to be included in these rollouts. Here’s what you actually need to know, without the hype.

The key takeaways

• Agentic e-commerce lets an AI agent buy on your behalf, but always within the limits of an authorization you grant it, either at the moment of purchase or in advance
• It runs on technical protocols that are still young (ACP, UCP, AP2) and not yet standardized with one another
• OpenAI pulled its built-in payment feature from ChatGPT in March 2026, just six months after launch: the ground is still shifting
• Shopify turned on its Agentic Storefronts feature by default for its U.S. merchants as of March 2026, with no setup required
• Google announced in May 2026 that it’s expanding its UCP protocol to Canada, a concrete signal for merchants here

What Is Agentic E-Commerce?

Agentic commerce builds on the broader principles of agentic AI: an agent that searches, compares, and buys a product for you, right inside a conversation. You're no longer searching Google yourself or comparing ten open tabs. You describe what you want, and the agent handles the research and comparison, up to presenting you with a purchase to approve.

The difference from the AI-assisted e-commerce we already know (personalized recommendations, customer service chatbots) is fundamental: in agentic commerce, the AI agent doesn't just suggest, it transacts. But transacting doesn't mean acting without you: it's the mandate you've given it, whether narrow or broad, that determines how far it can go on its own.

The Difference from Classic AI-Assisted E-Commerce

A chatbot that recommends a product still leaves you to click, compare, and pay yourself. A transacting agent can shrink that step down to a simple cart approval, or even remove it at the exact moment of purchase, but never without your consent. On ChatGPT, for example, you still have to tap "Buy" and confirm delivery and payment details for every order, even when the agent has done all the research legwork beforehand.

Only Google's AP2 protocol offers a truly autonomous mode, called "Human Not Present": you sign a precise mandate in advance (e.g., "buy these shoes if the price drops below $100"), with biometric authentication to confirm your intent, and the agent then completes the purchase without reconfirming, but always within the strict limits of what you authorized upfront. It's this shift, between real-time approval and pre-established authorization, that truly sets agentic commerce apart from everything else, not the absence of consent.

How Does Agentic Commerce Work? The Protocols You Need to Know

Agentic commerce runs on technical protocols, standards that let an AI agent, a merchant, and a payment provider understand each other. Without them, every agent would have to negotiate case by case with every merchant site, which would be unmanageable at scale. Five standards dominate the landscape as of mid-2026, and they don't all play the same role.

ACP, UCP, AP2, MCP, x402: What Do These Standards Do?

These protocols aren't competing in a zero-sum game: UCP and AP2 are designed to interoperate, and Mastercard has confirmed it's participating in all four major standards at once. A merchant likely won't have to pick one side. They'll need to follow several standards in parallel for a few more years.

Agentic Commerce vs. Traditional E-Commerce: What Changes

The shift to agentic commerce doesn't just change the buying interface, it shifts who does the searching and comparing. Here are the concrete gaps between the two models.

For a merchant, the most concrete consequence is this: your product listings now need to be as readable by a machine as by a human. Well-written marketing copy that's poorly structured (price, availability, variants left untagged) becomes invisible to an agent, even if it's perfect for a human reader.

Real Examples of Agentic Commerce

What Already Exists

OpenAI was first to take a shot at it. In September 2025, ChatGPT launched Instant Checkout: U.S. users could buy directly from Etsy sellers without leaving the conversation, confirming each order with one click, with a million Shopify merchants announced to follow. The result by March 2026: fewer than 30 Shopify merchants were actually live, and OpenAI pulled the feature, acknowledging that the initial version didn't offer the level of flexibility it was aiming for. ChatGPT refocused on product discovery rather than the transaction itself.

Google picked up the baton. In May 2026, at Google I/O, the company launched Universal Cart, a persistent cart that follows the user across Search, Gemini, YouTube, and Gmail, built on the UCP and AP2 protocols. Perplexity also rolled out its own instant-purchase feature.

This back-and-forth between launches and pullbacks captures where agentic commerce really stands: the technical foundations are moving fast, but real consumer adoption is advancing more cautiously.

Agentic Storefronts: The Shopify Case

Shopify turned on its Agentic Storefronts feature by default for all eligible merchants selling in the United States as of March 2026, with no sign-up required. The Shopify Catalog automatically structures and pushes product data (titles, descriptions, prices, inventory, shipping) to ChatGPT, Google AI Mode, Gemini, Microsoft Copilot, and Meta, in real time and with no app to install. Merchants don't have to choose between ACP and UCP. Shopify absorbs that technical complexity behind the scenes, notably as a development partner on Google's UCP.

One important detail for merchants: on ChatGPT, the purchase isn't completed directly inside the conversation. The customer is redirected to the merchant's own checkout, in an embedded browser or a new tab, which lines up with OpenAI's retreat from native payment described above. On Google AI Mode, Gemini, and Microsoft Copilot, direct in-channel payment remains possible if the merchant enables it. No additional Shopify fees apply to these sales beyond standard processing fees.

The numbers Shopify has published give a good sense of how fast things are moving, as long as you read them with the right timestamp in mind. According to comments from president Harley Finkelstein on the first-quarter 2026 earnings call, traffic to its stores from AI channels had multiplied eightfold year over year, and orders from AI-driven searches nearly thirteenfold. That pace has since slowed: on the second-quarter 2026 earnings call in early August, the company instead reported AI traffic and orders having tripled year over year, still strong growth, but noticeably less dramatic. The two measures don't cover exactly the same scope, but the direction is the same: AI's share of Shopify sales is growing fast, at a pace that's leveling off.

For merchants not on Shopify (Magento, BigCommerce, or a custom platform), a separate "Agentic Plan" lets them upload their product catalog and access the same infrastructure without migrating their store.

Agentic Commerce in Quebec and Canada: Where Do Things Stand?

Canada isn't leading the pack on enterprise AI, but the gap is closing, and agentic commerce is only just starting to include the country in its rollout plans.

According to Statistics Canada, the share of Canadian businesses using AI has tripled since the second quarter of 2024, and 27.8% of businesses with 100 or more employees reported having used AI over the past 12 months as of the second quarter of 2026. Deloitte, for its part, confirms that Canadian business adoption of AI is lagging behind global peers, even though the foundations (talent, research) are solid.

On the online shopping side, Quebec consumers' appetite is beyond doubt. Université Laval's NETendances 2025 survey found that 82% of Quebecers made an online purchase last year, a historic high, up 8 points from 2024. Notably for merchants here: Amazon's share of online spending dropped from 64% to 54%, to the benefit of Quebec and Canadian merchants, who now together capture nearly a third of that spending.

The clearest signal yet for Canadian merchants: Google announced in May 2026 that UCP-powered payment is expanding from the United States to Canada and Australia in the following months, ahead of the U.K. In other words, Canada is no longer left out of the first wave, it's becoming one of the next targeted markets.

How an SMB Can Get Ready for Agentic Commerce

You don't need to overhaul everything at once. Here are the concrete steps that prepare an online store without wasting budget on technology that's still unsettled.

• Structure your product listings: IDs, prices, availability, and variants need to be machine-readable (Schema.org structured data, up-to-date CSV or JSON feeds), not just readable by a human customer
• Check whether Agentic Storefronts is active for you: if you're on Shopify and selling in the U.S., it's probably already on. If not, go to Sales Channels > Agentic to turn it on and choose your channels
• Check how your brand shows up in AI answers: ask ChatGPT or Gemini to recommend a product in your category and see whether your business comes up
• Don't rush into a full technical integration: the standards are still changing fast (the Instant Checkout pullback proves it), better to stay agile than sink a big investment into a protocol that could be revised
• Review your terms of sale to explicitly cover purchases initiated by an agent on a customer's behalf, particularly around returns and disputes

What to Remember Before You Get Started

Agentic e-commerce isn't a stable reality yet, and that's exactly why it's worth paying attention to now rather than waiting until it becomes unavoidable. OpenAI pulling Instant Checkout after six months, and Shopify's growth rate slowing between Q1 and Q2 2026, both show that even the biggest players are moving by trial and error. For a Quebec SMB, the most valuable move today is making sure your product data is structured and readable, by both humans and machines.
