What proportion of Americans have likely visited Canada (or Mexico) at least once?

[Capsicum]

"Mexico was the top U.S. international destination last year, with a record 25.9 million visitors from the U.S",

According to an article from 2015.

Canada got about 11.5 million US visitors.

Also, it seems like according to these stats, roughly for the past generation or so, Canada gets about 10 million American tourists yearly.

It's hard to tell how many people are repeat visitors versus new ones, and averaged over the lifespan of the typical American, would the number of Americans who visited either Canada or visited Mexico at least once in their lifetime make up a majority of the population or not?
