Ontario is not currently in use for newborns in the United States: fewer than five babies received the name in 2025. Its story lives in the historical record below.

Since 1967, 877 American babies have been named Ontario. Its peak came in 1991, when 35 newborns received the name, the signature sound of the 1990s.

The chart above shows the full history: the popularity view (births per 1,000 babies) is the honest comparison across generations, since total US births have changed enormously since 1880.
