A new immigrant arriving at Pearson airport does not take the same path as you, who are a Canadian citizen. He goes through the first checkpoint and, at the second, finds himself among employees who of course speak English and French. Then he is directed to a specific location to obtain initial services. He is welcomed to Canada and given contacts in the anglophone, francophone, or other communities.
This kind of matching occurs at the airport, and that is where immigrants will see what the situation is.
