Tracker
Lake America adoption tracker
Who calls it Lake America, who still says Lake Ontario, and when we last checked. We verify against a primary source or major reporting before recording a change.
Where things stand
We track 6 institutions and platforms. 4 of them show Lake America to users in the United States; 4 use Lake Ontario in at least one jurisdiction they serve. We do not publish a share or percentage of “total adoption” — there is no complete list of everyone who labels a lake, so a denominator would be invented.

How we score adoption
A row changes only when we can point at a primary document or reporting from an outlet we would cite by name. Company blog posts and government pages count as primary; a screenshot or a social post does not. Each row carries its own re-check date, so a stale row is visible as stale rather than hidden behind a sitewide “last updated” stamp.
Where a platform shows different names in different countries, we record both views rather than picking one. Where we cannot source a position, the row says so and stays empty — we would rather leave a gap than guess.
Source monitoring
Once a day an automated check visits each cited source page and notes whether it answered and whether its text has moved since the previous check. That is a flag for a human to read the page again — nothing more. A changed source page never changes a row’s recorded name on its own; every position in this table is set by an editor after reading the source, and the dates shown (“status since” and the re-check date) are human-set.
Why can two people see different names?
Geographic names are not always global. Countries maintain their own official name databases, and private map platforms can choose how to label features for different audiences. In this case the U.S. made a domestic change, Canada did not, and some platforms decided to show different labels to different users.
Frequently asked questions
- Who calls Lake Ontario Lake America?
- U.S. federal systems, starting with the Geographic Names Information System, plus Google Maps and Apple Maps for users located in the United States. Canada, MapQuest and most of the rest of the world still use Lake Ontario.
- Why do two phones show different names for the same lake?
- Google and Apple label contested place names by the user's country rather than picking one global answer. The pin sits in the same place; only the text under it changes.
- Does MapQuest use Lake America?
- No. MapQuest said it would keep Lake Ontario, and TechCrunch reported on Sep. 2, 2026 that the app reached No. 1 overall in the U.S. App Store afterward.
- How often is this tracker checked?
- Every row carries its own re-check date. We only record a change after we can point to a primary source or major reporting, and we date the check rather than claiming the whole site was re-verified at once.
