Just because those people are not coming to Canada doesn't mean they don't exist anymore and won't impact the environment

The country where they are from is most likely suffering way more and is definitely more dense in population than Canada is. We should help Canada get better by accepting more immigrants and find ways they can contribute to helping our country by paying foreign taxes, restrict the number of properties they buy and make sure they are needed here in high demand professions and not taking someone else's job or staying unemployed.
