This seems a little racist and has little to do with "green". When every so-called "ethnic" that goes into a "majority culture" store or venue and feels warm and friendly, then maybe you can propose telling others what do do with their stores.

French is also an official language, so why privilege English over French? And why should non-English signs be removed? We have many visitors and tourists from other countries and seeing signs in their own language makes this a more welcoming place to come to. And there isn't any requirement that Immigrants be fluent in English before they arrive. Most do learn English once they come, although there are exceptions and these are often elderly folk. Cultural differences are a part of Canadian society. Even among English-speaking Canadians, there are cultural differences between different regions. So lets accommodate and celebrate the differences, not try to eliminate them.

@AWilliam: we don't have one common language. In Canada we have 2 official languages and dozens more unofficial languages.

Excellent idea. The present system creates parallel societies and atomizes neighbourhoods into ethnic/racial enclaves and isolates Canadians who happen to live in an ethnic community. Conducting any wide-scale campaign always runs into 'cultural differences', a euphemism for foreigners who don't understand, don't care about, and cannot relate to local issues. Affirming our commitment to one common language would be a great start in building a better society.

I'm sorry Jim but I'm not on the same page here. Immigrants are encouraged to learn to speak English, and they generally do - but removing signs in other languages will simply create an unfair barrier for those who are still learning, or who are simply too old to make a complete transition. How does it hurt you if non-english signs persist? Why can you not feel "warm and fuzzy" already going into a store that sells food that you're not familiar with? How do you think immigrants would feel if you made their already-unfamiliar surroundings even more foreign to them? My "green and strong" community needs diversity of all types to remain resilient.

I think your idea is the exact opposite of a "meltingpot". Accepting others languages, religions and cultures is what makes Canada a melting pot. Taking this opportunity away from new immigrants will only make them feel like they just moved to the USA
