MapQuest says no to Trump's Lake Ontario rename, briefly tops App Store over Google Maps

MapQuest, a U.S.-based navigation company with an office in Guelph, Ontario, has refused to adopt the Trump administration's renaming of Lake Ontario to "Lake America," posting the message "We're not changing it" on its official Bluesky account the same day President Donald Trump signed the executive order.

The order, signed Thursday, August 27, 2026, came two days after Trump first floated the idea publicly on August 25, against the backdrop of an ongoing Canada-U.S. trade war (Reuters). The renaming of Lake Ontario follows a pattern set by the administration's earlier rebrand of the Gulf of Mexico in 2025 — a change MapQuest also declined to implement (The Globe and Mail).

Doug Berger, general manager of MapQuest, oversees a company of roughly 50 employees with about 40 million monthly users. MapQuest is owned by System1, its parent company, which maintains an office in Guelph, Ontario (The Globe and Mail).

MapQuest's response went beyond a single social media post. The company posted a map still labelled Lake Ontario in direct response to the executive order (WXYZ Detroit / Facebook), and replied to posts on the platform discussing the new name (PCMag UK). It also launched a web tool at gulfof.mapquest.com/lakeontario letting users generate and share custom names for Lake Ontario. Within the tool itself, the lake was renamed "We're not changing it" (Yahoo News). Users created and shared their own variations, including one elaborate entry: "Lake I've been staring at maps of Lake Ontario for the last week so imagine my surprise at this recent turn of events" (gulfof.mapquest.com).

MapQuest's Lake Ontario page describes the body of water as the easternmost of North America's Great Lakes and the smallest by surface area, stretching roughly 193 miles (311 km) east-to-west and up to 53 miles north-south (MapQuest).

The commercial impact of the refusal was immediate. MapQuest gained hundreds of thousands of new users over the weekend following the executive order. It first became the second-most popular navigation app in Apple's App Store, then overtook Google Maps for the No. 1 spot (The Globe and Mail).

That surge came as Google, by contrast, announced on Saturday that it had begun rolling out changes to how its maps label Lake Ontario, complying with the executive order (CBS News / Facebook).

The divergent responses from MapQuest and Google bring a familiar question of Canadian federalism into focus: where jurisdiction over geographical naming actually lies. The U.S. Board on Geographic Names can rename features on U.S. federal maps, and a foreign executive order carries no legal weight in Canada. But digital map providers operate across borders, and their labeling decisions shape how millions of people encounter geographic reality daily. For Canadian users, seeing "Lake America" on a platform like Google Maps — or, conversely, seeing "Lake Ontario" preserved on MapQuest — is less a cartographic detail than a signal about which sovereignty a platform chooses to honour.

The Ontario government and federal officials in Ottawa have not, according to the available reporting, issued formal responses directed at the mapping companies specifically. The broader trade dispute between Canada and the United States, which prompted Trump's initial musings about the rename on August 25, remains the policy backdrop against which these corporate decisions are being read.

For a company of MapQuest's scale, the decision to publicly defy a U.S. executive order involves a different calculus than it would for Google or Apple. System1, MapQuest's parent, has Canadian operations through its Guelph office, which may factor into how the company handles competing pressures from both sides of the border. The App Store surge suggests a consumer market in which naming has become a stand-in for broader political sentiment, whether patriotic, defiant, or simply amused. Whether that download bump translates into sustained user retention is a separate question that the current data cannot answer.

What is established is that a mid-tier navigation app, by holding a line on a geographic name, briefly surpassed the dominant player in mobile mapping. And that the question of what to call a lake shared by two countries has become, at least for now, a measure of where companies and consumers place their allegiance.
