How should a plan handle province targeting in Canada?

How do you target Canadian provinces in programmatic?

A province is a geography setting on the line item or campaign. The site list says where an ad may appear; location targeting says who may see it. In Display & Video 360, the geography targeting help (opens in a new tab) says to "Use regional targeting to search for states, cities, and zip codes," and that proximity and regional targeting can be combined: "Both types of targeting can be used at the same time." The location targeting page (opens in a new tab) adds that buyers can "select locations to exclude in your line items if you don't want your ads to show in specific regions."

In the bid request, a province travels in the Geo object. The OpenRTB 2.6 specification (opens in a new tab) defines Geo.region as a region code using ISO 3166-2, which gives codes such as CA-ON for Ontario and CA-SK for Saskatchewan. The buying platform matches that region, or its own location estimate, against the line item's geography.

Google Ads frames location around two signals. Its page About targeting geographic locations (opens in a new tab) separates "Where your users are located or regularly located (physical location)" from "Locations your users have shown interest in (location of interest)." A province campaign that should reach residents only needs the presence setting confirmed, which the hub's step by step section covers.

How do language and population differ by province?

Canadian Heritage's official languages statistics (opens in a new tab), drawn from the 2021 Census and updated on the page in August 2026, give each province's population by first official language spoken. The English side of that table gives each province's count of people with English as first official language spoken. French figures by province are on our French Canadian advertising guide.

Three planning facts come out of the table. Quebec's English-speaking population is about the size of Manitoba's, yet it is under 15 percent of Quebec, so an English only plan reaches a minority there. New Brunswick is the one province where both language lines carry real weight. And Saskatchewan and Newfoundland and Labrador are close to fully English by this measure, so French creative there serves small communities rather than the provincial audience. Census figures are from 2021; for a current population count use Statistics Canada's quarterly estimates.

Which provincial rules affect regulated advertisers?

For regulated products, a national plan is a set of provincial plans. Health Canada's page on cannabis in the provinces and territories (opens in a new tab) says "Provinces and territories are responsible for determining the sale and distribution of cannabis within their jurisdictions," and lists a different legal age in Alberta and Quebec from the rest of the country. Age, language and product rules can change from one province's line to the next.

These rules attach to the advertiser and the message, so province targeting is how a buyer puts them into practice. An age gate set at 18 for the whole country sits below Quebec's legal cannabis age of 21; separate province lines let each one carry its own age, language and claims. An offer from an operator in Ontario's regulated internet gaming market is a case for a line set to Ontario alone.

How accurate is province level geotargeting?

Google says the same thing in both of its buying tools. Display & Video 360 location targeting "is based on a variety of signals, including users' settings, devices and behavior on our platform," and "Because these signals vary, 100% accuracy is not guaranteed in every situation." Google calls it "Google's best effort to serve ads to users who meet your location settings." The Google Ads page uses the same sentence about accuracy. Neither page gives an error rate for provinces.

Provincial borders run through shared media markets: Ottawa and Gatineau across the Ottawa River and Lloydminster, which straddles the Alberta and Saskatchewan line. Impressions just across a border are an expected result of signal based targeting, not a setup failure. Our programmatic geo targeting guide explains the location sources behind it.

Should budgets follow population by province?

Population is the honest first draft of a provincial split, because it is public and easy to explain. It stops being the right answer as soon as the business is uneven: a retailer that ships faster in the west, a service sold in three provinces, or a French offer that only exists in Quebec. Inventory is the second correction. Display & Video 360's Inventory Availability report (opens in a new tab) is built to "find the predicted number of impressions that match specific targeting criteria," which shows whether a province line can spend its share on the chosen sites.
