Canada

They "can" but it's rather useful as all hell to know English while living in Quebec. It's a struggle to find anyone born in the province who is not bilingual for this reason.

It is very one sided overall.

How many different languages are spoken within a 1000 km of the UK? How large are those communities? How many of the people from other communities also speak English? Ask the same questions for Canada and the answers are 3 with any significant population, less than 10% for one and is spread across two countries while being the official language of the third country for the other, and the vast majority of them for two of the three countries.

The North American anglophone attitude is very pragmatic, as is the British anglophone's. The same applies for the North American francophone attitude, although they like to complain like they aren't a minority, both nationally and across the continent. And if a company from Quebec wants to expand outside the province's borders, requiring their employees to speak French is going to reduce their candidate pool and hence increase their payroll costs, or their leaders are going to have to learn English which, as we've already discussed, they already mostly do.

You and I can talk about what we'd like to see, or how things should be, and we might even agree about it. But this is how things are.
