Canadian Google Merchant Centre needs CAD pricing, French-language feeds for Quebec, and a Walmart Canada feed setup that most AU/US brand expansion checklists miss

Shopify generates product feeds in the store's default currency by default. To serve a CAD-currency feed to Google Merchant Centre for Canadian Shopping campaigns, the brand must either use Shopify Markets to set Canada as a separate market with CAD pricing and configure the Google & YouTube channel to export the Canadian market feed, or use a third-party feed tool (DataFeedWatch, Feedonomics, or GoDataFeed) that can pull the CAD price from Shopify's multi-currency pricing and generate a separate feed for submission to a Canadian Google Merchant Centre account. The CAD feed must be submitted to a Merchant Centre account with Canada as the target country.

A supplemental feed for Quebec French is a secondary feed submitted to Google Merchant Centre that overrides specific attributes (title, description, product_type) for Canadian French locale targeting. The supplemental feed uses the same item IDs as the primary feed and submits French-language values for the attributes being overridden. In Merchant Centre, the supplemental feed is linked to the primary feed and the override is applied for Canadian French (fr-CA) language targeting. The French-language titles should be translated from the English primary feed titles, not machine-translated without review: Google Shopping's query matching for French-language queries depends on the quality of the French title.

Google Merchant Centre for Canada allows brands to specify whether the prices in the feed are tax-inclusive or tax-exclusive, and to configure tax rates by province. For most Canadian Shopping setups, feed prices are submitted as tax-exclusive (pre-tax), and Google's tax configuration in Merchant Centre specifies the applicable rates by province. This approach allows Google to display the correct tax-inclusive price for buyers in each province without requiring the brand to submit a separate price for each province. The critical requirement is that the Merchant Centre tax settings match the tax rates the brand actually charges at checkout: a mismatch between the Merchant Centre tax configuration and the checkout tax creates a price mismatch that triggers policy issues.

Walmart Canada Marketplace feed submission is managed through the Walmart Supplier Portal and Seller Centre. The brand must first register as a Walmart Canada Marketplace seller, which requires a Canadian business registration (BN) or approved import account. Once approved, product feeds are submitted as category-specific spreadsheet templates or via Walmart's Content API. The feed specification includes Walmart-specific required attributes (Walmart item ID, product group, shelf description) that differ from Google Shopping attributes. A brand that has already built a Google Shopping feed can use the Google feed as the source of truth for product data and generate a separate Walmart-formatted export using a feed management tool or custom mapping.

A Canadian Google Merchant Centre account is linked to a Google Ads account through the Merchant Centre account settings under "Linked accounts." Once linked, the Google Ads account can create a Performance Max campaign with a product feed goal, selecting the Canadian Merchant Centre account as the product data source. The campaign targeting should be set to Canada, with language targeting including both English and French to capture Quebec traffic. The Performance Max campaign will use the product feed to generate Shopping ads, display ads, and other formats automatically. The feed quality directly affects which products are eligible for Performance Max placements.
