said by yyzlhr:Mandarin and Arabic are not official languages. Although we have lots of immigrants who speak it, the expectation is for them to learn either English or French if they intend to live here permanently.
Is that the reality, though, in Vancouver and so forth?
said by yyzlhr:Also many Asian economic powers such as China, Hong Kong, and Korea are very keen on ensuring their future generations are fluent in English.
That is true, as English has become the de facto leading language for business, medical and scientific research, and so forth.
As I've documented here on DSLR in the past, many scientific journals based in China now are published in the English language!
