Seems that they use "pension" more than we french, but still the expression seems "plan de pension"

Makes more sens than french canadian though.
épargne pension is more common in Belgium, though.
Although, as Belgian, plan pension doesn't seem that odd to me.
(plan pension is a literal translation from dutch: pensioen plan)
Never heard it in Quebecois French, Anglicisms like that tend to be continental French in my experience. Or Chiac.
Yes, for English speaking Canadians a "pension plan" is a common phrase. No idea about French-speaking Canadians.
