Last time I was in Vancouver I noticed more signs with translations in Sḵwx̱wú7mesh than French...
However that might be because I am an anglophone from Ontario and my mind filters out the French language on signs if an English equivalent is present.
No, you were probably right. About the only French in Vancouver is in federal facilities: so, in practice, the airport and some parts of the port that nobody in the general public would ever go to.
