Google Maps has changed, or is rolling out a change to, how it labels Lake Ontario for users in the United States. Bloomberg reports that Google Maps relabeled the lake as “Lake America” for U.S. users, citing an announcement by Alphabet Inc. The company said the move was prompted by a change in the official U.S. government geographic naming system, according to Bloomberg. The Google blog text included in the cluster says the U.S. Geographic Names Information System, or GNIS, formally changed the name for “Lake Ontario” to “Lake America” in the United States. Google’s stated handling is jurisdiction-specific. According to the Google blog text, Maps users in the U.S. will see “Lake America,” users in Canada will continue to see “Lake Ontario,” and users outside the U.S. and Canada will see both names. The company framed the update as an application of its existing policy for bodies of water whose names vary by country. Google said it updates Maps to reflect name changes in official government sources, and that GNIS is the relevant source for U.S. naming. Bloomberg adds political context: the outlet reports that the change followed President Donald Trump saying he would rename the lake amid a trade spat with Canada. The provided Google blog text does not mention that context; it describes the trigger as the GNIS change and the map-label policy. The practical effect is that Google Maps will present different labels for the same body of water depending on where the user is located. In Google’s description, the Lake Ontario/Lake America change follows its long-standing policy for bodies of water with names that vary from country to country. Who benefits: Too early to tell who benefits. Google says U.S. users will see “Lake America,” while Canadian users will continue to see “Lake Ontario.” Who's exposed: Users in different locations may see different labels for the same body of water in Google Maps. Canadian users will continue to see “Lake Ontario,” according to Google’s statement.
