Why would they be illegal? Their anti-competitive nature vis a vis small businesses?
Yes.
Vancouver is unique. We voted overwhelmingly in 1969 to ban any form of freeway, controlled access highway or thruway for ever. As a result we are the world's largest parking lot; traffic has its own rate of flow which usually causes Americans to lose it and start shooting, which is also illegal.
We have been waging war with the internal combustion engine since then, and can claim some victories as more and more of discover buses and sky train are not only free (Actually $55 a year) for seniors, but is pretty handy. (People exiting buses here call out "thank you, driver" - always have.)
So in keeping with this "green" attitude is a war against parking lots and the space they take up, which could be used for housing or green space.
Further, along with most of Canada, we like small, intimate businesses here. The single owner confection store is still a reality - 7-11 etc. is here but they are American culture not ours. Traditionally Canadians want to buy from people, neighbors. Our entire dairy industry is based on the family farm, over 12% is harvested by hand by the Amish people in Ontario..and we want it that way.
The greatest difference between our two countries is that you arm yourselves against one another, while Canadians pay for each others medical bills. People have long accused us of having no culture and in movies, music & TV we don't, we carbon copy US garbage. Our culture is exhibited on the head signs on buses that say "Sorry" out of service, insist on having doors with locks but seldom use them.
Here's how Canada would deal with the border crisis along your southern flank. The federal government would allocate $ to the affected provinces to provide temporary housing and medical aid. ATCO corp would be tapped from a few hundred portable homes, and the people would begin fund drives etc.
BSA agents would fan out with packages of emergency food, sanitary wipes, toothbrushes etc. and say "welcome to Canada" asylum seekers and a long, formal process that can take up to three years will begin to establish a bona fide claim. Once that is done, they are given landed immigrant status and sorted out for training or employment.
This has been our policy since 1992.
The number of crimes associated with this process: 0
Percentage of applicants accepted - 75% on average.
In closing, you will know that Canada accepted 64,000 Syrians a few years ago. At the time people in this forum were telling me "They will rape your women".
The number of crimes suspected by these people: 0
One Syrian was months away from an MD. He completed it and went to work for a local hospital as a resident where he stayed long after he needed and may still be there.
When he isn't saving lives in the emergency ward, he's working with Indigenous people and their medical issues in an open (free) clinic.
Beginning with the French who were unwanted at home, to the negro slaves who made their way along the "underground railroad" to the "commie" Hungarians to the Vietnamese boat people to American draft dodgers to the latest round of "rejects" we appear to have built a rather fine country out of people the rest of the world didn't want.
As long as we see these images from the US, it must be told and retold that the son-of-a-bitch vilifying these people made his billions of their illegal labors.
