Well the reality is very simple and straight forward there Whoever he is, he cannot use Nepali as a primary language for communication in Canada so for anyone whose native language is not English has to state English as a primary language for written and verbal communication in Canada. The rest of the other languages he knows becomes second, third (and so on) language. For him to state Nepali as a primary language in Canada there should be several million people in Canada who can understand Nepalese language. For example, in the Canadian province of Quebec, almost half of the Quebec residents state French as their primary language for written and verbal communication and english as second and other languages as third and so on because there are several million people whose understand French and they speak and write in French. This doenst make anyone who speak and write in French any worse than the ones who speak and write in English and vis versa. I dont think there are much serious issues to debate on when anyone states other languages as their primary language of communication when their native language is not English. It becomes much more trickier when: What will the children of immigrants do who have arrived in US or Canada or UK when they were very young or born in US or Canada or UK ? Should they state Nepali as their primary language of communication in these countries ?
