AI shopping agents: is your online store ready for 2027?

AI shopping agents are assistants such as ChatGPT, Gemini and Google's AI Mode that research products on a shopper's behalf and, increasingly, help them buy. Heading into 2027, the honest picture for a Canadian online store is this: AI assistants are already a real way for people to discover products, but buying inside the chatbot is still early, limited and mostly reserved for large retailers. The stores that benefit first are not the ones with the cleverest AI integration. They are the ones whose product data, policies and checkout are clear enough for a machine to read and for a cautious human to trust.

Key takeaways

• Discovery is live, checkout is early. Assistants already recommend products and send shoppers to stores. Buying without leaving the chat is still limited to selected merchants.
• ChatGPT stepped back from in-chat checkout. In March 2026 OpenAI scaled back Instant Checkout and now sends most shoppers to the merchant's own site to pay.
• Google is pushing hardest. Its Universal Commerce Protocol (UCP) powers a buy button in AI Mode and Gemini, and it has started reaching Canadian shoppers through large launch partners.
• Your product data is the new storefront. Clean feeds, structured data and consistent prices decide whether an agent can recommend you at all.
• The visitor an AI sends you is ready to buy. They land on a product page, not your homepage, so that page and your checkout have to do all the work.
• Most small stores should not build a custom AI integration in 2027. Get the foundations right and let your platform handle the protocols.

What "agentic commerce" actually means

"Agentic commerce" is the industry name for shopping that an AI agent carries out for a person, rather than the person clicking through search results themselves. The term gets used loosely, so it helps to separate three levels that are often blurred together.

1. Discovery. The shopper asks a question - "a waterproof winter boot for wide feet under $200, delivered to Calgary before Friday" - and the assistant compares options and links to the stores that fit. The purchase still happens on your website.
2. Assisted checkout. The assistant completes the purchase inside its own interface, passing the order and a payment token to the merchant through a standard protocol. The shopper never visits your site.
3. Delegated buying. The shopper gives the agent standing permission within limits - "reorder printer ink when it runs low, never above $60" - and the agent buys without asking each time.

Almost everything that matters for a small Canadian store in 2027 happens at level one. Levels two and three exist, but they are still being rolled out by the largest platforms, with the largest retailers first.

Where things stand at the end of 2026

This market has moved fast and changed direction more than once, so the details below are dated on purpose. Check them again before you make a large decision.

ChatGPT: from checkout back to discovery

OpenAI launched Instant Checkout in ChatGPT in the fall of 2025. It let shoppers in the United States buy from selected merchants without leaving the conversation, using the Agentic Commerce Protocol that OpenAI developed with Stripe. In March 2026 the company scaled the feature back after limited uptake from merchants. ChatGPT now concentrates on helping people find products and generally sends them to the merchant's own website to pay, with some purchases moving into retailers' apps inside ChatGPT. The protocol specification itself continues.

The lesson is useful for any store owner: even the best-funded AI company found that shoppers prefer to pay where they already have an account, saved payment details and a sense of who they are buying from. That is your own checkout.

Google: UCP and the buy button in AI Mode and Gemini

In January 2026 Google introduced the Universal Commerce Protocol, an open standard it developed with Shopify, Etsy, Wayfair, Target and Walmart. UCP powers a checkout feature on eligible product listings in AI Mode in Google Search and in the Gemini app. The shopper pays with Google Pay, and the store remains the merchant of record - you still own the order, the customer relationship, refunds and support.

Google has begun bringing this direct checkout to Canadian shoppers, with retailers such as lululemon and Shoppers Drug Mart among the first. For everyone else, access is still by approval: a store has to complete a technical integration through Google Merchant Center and be accepted before the buy button appears on its listings.

Payments are getting ready too

Card networks have launched programs, such as Visa Intelligent Commerce and Mastercard Agent Pay, that let an AI agent pay with a tokenised card that the cardholder has authorised, within limits they set. You don't need to do anything with these directly. They matter because they remove one of the biggest objections to agent purchases - "what stops the bot from spending my money?" - and that will make level two and three shopping more common over the next few years.

Why discovery matters more than checkout right now

It is tempting to chase the shiny part - a buy button inside a chatbot. The part that already pays is quieter. When an assistant recommends your product, the person who clicks through has usually described exactly what they need, compared several options and narrowed the list to you. That is one of the highest-intent visitors a store can get.

But that visitor arrives differently. They skip your homepage and your carefully designed brand story and land straight on a product page. If the price, delivery time and return policy are not obvious within a few seconds, they go back to the assistant and pick the next option. In an AI-driven journey, every product page is a landing page, and it has to answer the questions the shopper already asked the agent.

Step 1 - Make your product data machine-readable

An AI agent can only recommend what it can understand. It reads your product pages, your structured data and, for Google, your Merchant Center feed. Messy or contradictory data means you are simply left out of the comparison.

• Add Product structured data to every product page, including the price in CAD, availability, brand, a GTIN or model number where you have one, shipping details and your return policy. Our guide to schema and structured data covers how this works.
• Set up a Google Merchant Center feed. Free product listings are available in Canada, and Merchant Center is the source Google uses for shopping in AI Mode and Gemini.
• Keep one version of the truth. The price and stock on the page, in the feed and in the structured data must match. Agents, like shoppers, lose trust in a store whose numbers disagree.
• Write product descriptions like a good spec sheet. Dimensions, materials, sizing notes, compatibility, care instructions and who the product is for. Agents match attributes to questions, and "premium quality you'll love" gives them nothing to match.

Step 2 - Let the right bots in

Many store owners block "AI bots" without realising that the label covers very different crawlers. Some collect data to train models; others fetch your page because a shopper is asking about your product right now. Blocking the second group means removing yourself from the answer.

• OpenAI uses separate crawlers: GPTBot for training, OAI-SearchBot for ChatGPT search results and ChatGPT-User when a user's request triggers a visit. You can block training while still allowing search.
• Google uses the normal Googlebot for Search, including AI Mode. The separate Google-Extended token controls use for Gemini model training and does not affect your Search listings.
• Check your firewall, not just robots.txt. Since mid-2025 Cloudflare has blocked known AI crawlers by default on newly added sites. If your store sits behind Cloudflare, review the AI crawler settings so you are not invisible by accident.

The wider topic of being cited by assistants is covered in our guide to getting found in AI search.

Step 3 - Put your policies where a machine can find them

When a shopper asks "which of these ships to Halifax by Thursday and has free returns?", the agent needs that information in plain text on your site. Policies buried in a PDF, an image or a pop-up are effectively missing.

• Shipping: delivery times and costs by province or region, cut-off times, and whether you ship to rural and northern addresses.
• Returns: the return window, who pays for return shipping, and how refunds are issued.
• Prices and taxes: show prices in Canadian dollars and make it clear how GST, HST or PST is applied at checkout. If any products ship from outside Canada, say whether duties are included.
• Language: if you sell into Quebec, French product information and policies are expected. Our article on English and French websites in Canada explains the structure.
• Proof: a real business address, a working contact method and genuine customer reviews on product pages. See how to collect and show reviews.

Step 4 - Fix the checkout people actually land on

Because ChatGPT now sends most buyers back to the merchant to pay, and because Google's in-chat checkout is not yet open to most small stores, your own checkout carries the sale. A shopper who arrives already decided should be able to pay in under a minute.

• Offer guest checkout. Forcing an account at the last step loses buyers who were ready to pay.
• Support express wallets such as Apple Pay, Google Pay or your platform's own one-click option.
• Show the full total early, including shipping and tax, before the final step.
• Make it fast on mobile. Many AI conversations happen on phones. Our guides to Core Web Vitals and e-commerce conversion go deeper.

Step 5 - Measure AI traffic separately

If you don't measure this channel, you can't tell whether any of the work above is paying off. Most of it is visible in ordinary analytics.

• In Google Analytics, look at referral traffic from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com, and group them into a custom "AI assistants" channel.
• Links from ChatGPT usually carry utm_source=chatgpt.com, which makes those visits and the sales they produce easy to isolate.
• Traffic from Google's AI Mode generally shows up as ordinary Google organic traffic, so judge it through Search Console and overall organic sales rather than a separate line.

Our guide to analytics for small business shows how to set up channel groups without drowning in reports.

Should you build for UCP or ACP now?

For most small Canadian stores, the honest answer for 2027 is no - not as a custom development project. The protocols are still changing, access is limited and the volume flowing through in-chat checkout is small compared with the traffic assistants already send to ordinary product pages.

• If you are on a major platform such as Shopify, let the platform handle the protocols. Check its AI and sales-channel settings, keep your catalogue clean and watch Merchant Center for eligibility notices.
• If you run a custom store, keep a clean product data layer - an accurate feed and complete structured data - so connecting to a protocol later is a small job rather than a rebuild. Our comparison of Shopify and custom e-commerce in Canada covers the trade-offs.
• A direct integration starts to make sense when you have a large catalogue, meaningful sales volume and a development budget, and when the program is actually open to merchants like you.

Trust, refunds and privacy don't change

In every current model the store stays the merchant of record. That means the obligations you already have - delivering what you sold, honouring your return policy, handling refunds and chargebacks - stay with you even when an AI took the order. An agent purchase is still your customer.

Order and customer details that reach you through an AI platform are personal information like any other, so the usual Canadian privacy rules apply. Update your privacy policy to mention that orders may come through third-party platforms and how that data is handled. Our overview of PIPEDA, Law 25 and CASL is a starting point; for anything specific to your business, talk to a lawyer.

Red flags: "agent-ready" offers to ignore

Every new channel attracts people selling shortcuts. Treat these with suspicion:

• "Guaranteed placement in ChatGPT." Nobody outside the AI company controls what an assistant recommends. Any advertising an assistant runs is sold through its own ad platform, not through an agency's secret method.
• Hidden text "for AI agents". Stuffing invisible keywords into pages is the same old spam, and search engines treat it as such.
• Rebuilding your whole store for a protocol you can't use yet. Spend that budget on product data, page speed and checkout, which pay off in every channel.

A 2027 readiness checklist

• A Google Merchant Center feed is live, approved and free of errors.
• Prices and stock match across the page, the feed and the structured data.
• Product descriptions include real specifications, sizing and compatibility.
• OAI-SearchBot and Googlebot can reach your product pages; firewall AI settings have been reviewed.
• Shipping, returns and tax information is in plain text and easy to find.
• Genuine reviews appear on product pages.
• Guest checkout and at least one express wallet are available.
• Product pages and checkout load quickly on a phone.
• An "AI assistants" channel exists in your analytics.

Frequently asked questions

What is agentic commerce?

Agentic commerce is shopping carried out by an AI agent on a person's behalf. At its simplest the agent researches products and links to the best fit; at its most advanced it completes the purchase inside its own interface, or buys automatically within limits the shopper has set. Most activity today is at the research and recommendation stage.

Can customers buy my products inside ChatGPT?

Generally not, for a small store. OpenAI scaled back its in-chat Instant Checkout in March 2026 and now usually sends shoppers to the merchant's own website to pay. ChatGPT can still recommend your products and link to them, which is where the real opportunity lies for most stores.

Is Google's AI checkout available in Canada?

It has started. Google has begun bringing UCP-powered checkout in AI Mode and Gemini to Canadian shoppers, with large retailers among the first. For other merchants access is by approval through Merchant Center, so check Merchant Center for eligibility rather than assuming it is open to you.

Should I block AI crawlers from my store?

Block the training crawlers if you prefer, but allow the ones that power search and shopping answers. For OpenAI that means allowing OAI-SearchBot even if you block GPTBot; for Google, Googlebot handles Search including AI Mode. Also check firewall settings such as Cloudflare's, which can block AI crawlers by default.

Will AI shopping agents replace my website?

Not in the foreseeable future. In every current model the store remains the merchant of record, and most AI-driven shoppers still finish their purchase on the store's own site. AI agents make your product data and product pages more important, not less.

How do I know if AI assistants are sending me sales?

Check referral traffic from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com in your analytics, and look for the utm_source=chatgpt.com tag on ChatGPT links. Grouping these sources into one channel lets you see visits, conversion rate and revenue from AI assistants over time.
