Google Maps has changed Lake Ontario to Lake America for US users
Developing story first seen 6 hours ago
Google Maps has renamed Lake Ontario to "Lake America" for users in the United States, following President Trump's executive order and a subsequent update by the US government's official place-names authority. The change extends the administration's renaming campaign into digital mapping databases, echoing last year's switch from "Gulf of Mexico" to "Gulf of America" and confirming that such changes are enforced through official naming registers rather than remaining symbolic.
Google says it updates Maps to reflect changes in official government sources, and in the US that source is the Geographic Names Information System (GNIS), which changed Lake Ontario's designation this week. As a result, US users will see "Lake America", Canadian users will continue to see "Lake Ontario", and users elsewhere may see both names displayed. Apple Maps has not yet made the equivalent change, though it adopted "Gulf of America" last year and is expected to follow suit.
- Google Maps now shows "Lake America" instead of Lake Ontario for US users
- Change follows Trump order and GNIS renaming this week
- Canadians still see "Lake Ontario"; Apple Maps hasn't updated yet
New here? Start with this
Google Maps has begun showing "Lake America" instead of "Lake Ontario" for people browsing the map from within the United States. The change follows an order from President Trump and an update to the Geographic Names Information System, the official body that decides what US government maps and records call places. Google says it simply mirrors whatever names appear in these official government sources, and it made a similar switch last year when the Gulf of Mexico became the "Gulf of America" for US users.
Lake Ontario is one of the five Great Lakes, sitting on the border between the United States and Canada, so any renaming has a cross-border dimension. Canadian users will still see "Lake Ontario" on their maps, while people elsewhere in the world may see both names displayed together, meaning the label someone sees can depend entirely on their location.
The story matters because it shows how disputes over place names, once largely symbolic, now play out directly on the digital maps hundreds of millions of people use every day. It also raises questions about how other companies, such as Apple, will respond, since Apple Maps has not yet made the equivalent change to the lake despite having adopted "Gulf of America" previously.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Supporters argue that a national government has the plain authority to decide what official name its own agencies and platforms use for geographic features within or bordering its territory, just as other countries maintain their own naming conventions. They see this as consistent with the earlier Gulf of America change, framing it as an assertion of national identity and sovereignty over how America presents its geography to its own citizens, rather than an attempt to dictate terms to Canada, since Canadian users still see Lake Ontario. They also note that mapping companies are simply following long-standing practice of mirroring each government's official naming database, which is a neutral, rules-based approach rather than editorial bias.
The case against
Critics argue that Lake Ontario is a shared international waterway bordering a close ally, and that unilaterally renaming it disregards Canadian sovereignty, historical usage and the goodwill that underpins the two countries' relationship, especially given recent trade and territorial tensions. They see the change as needlessly provocative symbolism that strains diplomatic ties for little practical benefit, and worry that erasing an Indigenous-rooted, centuries-old name in favour of an overtly nationalistic label sets a troubling precedent for how digital platforms can be used to project political messaging into everyday tools. They also caution that when tech companies automatically adopt government-mandated names without independent judgement, it normalises the use of neutral infrastructure, like maps, as instruments of political assertion.
Full account
Google has begun renaming Lake Ontario to "Lake America" for users of Google Maps in the United States, implementing an executive order signed by President Donald Trump earlier in the week. The change, which appeared late on Saturday, only affects how the lake is labelled for people browsing from within the US; those using the app in Canada continue to see the traditional name, while users elsewhere in the world are shown both.
The relabelling stems from an update to the Geographic Names Information System (GNIS), the US government's official register of place names, which Trump ordered altered as part of a wider dispute with Canada over trade tariffs — Ontario being the name of the Canadian province that borders the lake. It mirrors an earlier move from January 2025, when Trump directed that the Gulf of Mexico be renamed the "Gulf of America" in federal records, a change that Google, Apple and Microsoft all eventually adopted once the Department of the Interior formalised it.
Google says it updates its mapping products to match whatever a country's official government source specifies, and that this is simply the latest application of a long-standing policy of showing different names for bodies of water depending on where a user is located. Apple Maps and Microsoft's Bing Maps had not made the equivalent change at the time of writing, though both are expected to follow suit given their past adoption of the Gulf of America naming. Notably, even the GNIS database itself had not fully updated its own reference map as of Sunday morning, carrying a note that the change was still being processed.
The episode has reignited debate within open-source mapping communities such as OpenStreetMap, which underpins services including Uber and Lyft; that project maintains both the US and international names and lets individual platforms decide which to display. Not every provider has fallen in line: MapQuest publicly stated on social media that it would not be changing its labelling. Google's own statement on the matter was issued without an individual signatory attached.
Where outlets differ
One outlet frames the story with a more critical, exasperated tone toward the renaming exercise and its perceived absurdity, while the other adopts a more measured, factual register.
The Ars Technica-style account gives considerably more political and historical context, including the specific date of Trump's order (Thursday) and its link to the tariff dispute with Canada, and situates it alongside the earlier Gulf of Mexico/America renaming from January 2025 in more detail.
Only one source mentions the OpenStreetMap community debate and MapQuest's refusal to adopt the new name — the other source does not cover reactions from other mapping platforms or communities beyond noting Apple Maps' delay.
One source notes that even the official GNIS database map had not yet been updated as of Sunday morning, a detail absent from the other account.
The shorter source references Google's explanation as coming from 'a blog post,' while the other describes it as an 'unsigned statement' — a minor discrepancy in how Google's comment was characterised.
