If we go back to what is happening at the moment, I can tell you that all the migration policies, all that the United States is putting into place, and all the threats their president is making is not stopping people from organizing migrant caravans. This is not even about individual considerations anymore; these are definitely migrant communities deciding to form caravans to get to the United States. We make a mistake by thinking that we are an island in the centre of the world. Even if we were that island, people would still get on a boat to get here. We have seen that once again in the case of the Rohingyas.
I repeat that all the walls we may build will be of no use. Instead, we have to ensure that people can keep their dignity. As you say, Canada is a welcoming country. If Canadians found themselves having to flee their country one day, they would be very happy to find other countries open and generous towards them.
