I don't really care so much for the "lingua franca status of English" (even though it's the only language I speak fluently). While yes, this is one of Canada's main languages (not that we don't have a lot of Cantonese/Mandarin speakers too), China itself would be a good example that one can succeed without speaking the language which has the "lingua franca status"

Perhaps it's worth noting that the number of fluent Mandarin/Cantonese speakers in Canada is probably not much lower (as a percentage - ~4% in 2016 and I can imagine it's only increased since then) than the number of fluent English speakers in China (5%)

edit: 4% is actually the number of Canadians who spoke Mandarin or Cantonese as a first language in 2016 (which again, is likely higher now). The number of fluent combined Chinese language speakers is almost certainly higher then, even if just a little bit.
