I have been intrigued by the ethnologue database entry for Chinook Wawa speakers which reads: 10 to 100 including Canada, all over 50 years old (1962 Chafe). By the date of this information any speakers left have got to be over 86 years old.=20 You can find this information at http://nic2.hawaii.net/ethnolog/. I don't know the source cited, however.
