I did not say the program wasn't working. I'm not sure which program you mean, but I said a good chunk of the money we invest in immigrants does go for language training.
My sense is that the number of 55- to 64-year-olds exempt from language is not large. Historically people in that age cohort have done well, even though in some cases their mastery of the English language or the French language is limited, so I do not foresee there being any significant negative economic effect.
