Google Maps renames Lake Ontario to Lake America; MapQuest's refusal sends its app to No. 1

President Donald Trump's order renaming Lake Ontario as "Lake America" has split the major mapping platforms. Google Maps began showing the new name to users in the United States on Saturday, while MapQuest announced it would keep the original name — and promptly rode a wave of downloads to the top of the US navigation charts.

Google follows its government-name policy

According to AP, Google updated its mapping application after Trump ordered the change on Thursday. The company said in a blog post on Saturday that the decision follows its long-standing practice of adopting names recorded in the U.S. Geographic Names Information System (GNIS) for US users.

Under the rollout, people using Google Maps in the US see "Lake America," users in Canada continue to see "Lake Ontario," and users elsewhere see both names. Google took the same approach in 2025, when it applied Trump's order renaming the Gulf of Mexico as the Gulf of America.

AP reports that the order landed amid an escalating trade war that has led both countries to impose billions of dollars in added tariffs on each other's goods. TechCrunch adds that the renaming followed a breakdown in trade talks, with the US imposing new 50% tariffs on $20 billion worth of Canadian goods and Canada preparing to retaliate.

Ontario Premier Doug Ford answered the decree with a billboard-sized message on the Canadian shoreline reading "Lake Ontario. Now and Always," and, according to AP, Canadian leaders met the move with ridicule rather than outrage.

MapQuest refuses — and surges

MapQuest, which brands itself the "OG of online mapping," said on Thursday that it would not rename the lake, despite the executive order directing the Department of the Interior to update the US geographic naming service. The payoff was immediate, TechCrunch reports: by Monday morning the iOS app sat at No. 4 on the US App Store's top charts for non-game apps and No. 8 across apps and games. It also became the No. 1 navigation app in the United States and reached No. 2 overall in Canada's App Store by Sunday evening.

The company said it picked up "hundreds of thousands" of new downloads over the weekend and that usage climbed to 50 times normal levels. Third-party data from Sensor Tower, cited by TechCrunch, broadly confirms the spike: roughly 184,000 global and 162,000 US downloads in the week beginning August 24, each an increase of more than tenfold week-over-week, with US daily downloads rising 128% between August 26 and August 30.

"We took the same approach we did with the Gulf of Mexico: be part of the conversation, and give people an app that keeps the names they're familiar with," MapQuest General Manager Doug Berger said in a statement.

MapQuest also released a tongue-in-cheek online tool that lets users jokingly rename the lake to whatever they like and share the result on social media, reprising a gimmick it ran after last year's Gulf of Mexico renaming.

Apple has not moved yet

As of Monday morning, Apple Maps had not renamed the Great Lake and had not issued a statement about its plans, according to TechCrunch. Both Apple Maps and Google Maps did apply the Gulf of America change last year.

MapQuest itself is a 30-year-old property that has passed through AOL and Verizon before Verizon sold it to the advertising company System1 in 2019. Sensor Tower estimates its app has been downloaded 687,000 times worldwide so far this year, up 29% year-over-year, and 24.4 million times since 2012, with 97% of those installs coming from the United States.

Why it matters

The standoff shows how map labels have become a platform policy question rather than a cartographic footnote. Google's policy of deferring to official government name registries means a unilateral executive order instantly becomes the default view for millions of users — and because names are regionalized, Americans and Canadians now see different labels for the same body of water. The market response to MapQuest demonstrates real demand for a platform that declines to follow such changes, handing a decades-old underdog its biggest product moment in years. For platform operators, the episode sets an uncomfortable precedent: when names turn political, staying "neutral" by following official sources is itself a visible choice that users will judge — and vote on with downloads.
