I have a sure fire method for detecting Canadians out in the wild. Pay close attention to how they pronounce the word “resources”. If you hear the letter Z in there then they are probably Canadian.
For me it would be something like /ʌɪs aɪz ɡəˈɹæʒ ˈsɔːɹi ˌɹiˈzɔɹsɪz/.
strong emphasis on the out as "ooot" -- "figure it ooot, bud"
