Again Canada is dropping the ball and we are acting like the EU because of the heritage of the leaders. They all went to the same Private School or they are not part of the shakers of the world. Start with that line and add as many more as you need for the situation. The unlucky few that made it here (after a few years in a refugee camp) they are dumped into some low income housing project that is one step away from demolition and are expected to say 'Thank you, Sir' forever. The latest shooter has relatives that come from Pakistan and if their life was in the poor part of Toronto there are very limited options and most of them are illegal. Good for keeping all the beds in prisons full but that is about it.
If we cannot retrain them fast, keep the public safe before and after 'the debriefing', and look at skills that would be useful in repatriation a few years down the road as the education route that should be followed so language barriers need to be overcome, enter a computer that can translate as it receives the documents. Business programs would be what is on the menu for the day, trades useful in the day to day living as the trades that are needed for a fast reconstruction would be filled by 'migrant workers' who do the work in a decade and by that time the last of the 'refugees' have come home. Canada now has a bunch of 'teachers' that are our of work because the classrooms are empty.
If you want to keep them they need a rural setting and a way that leaves them owning something, like a business. Make the Great Lakes a fishery where the fish are fed by water bombers. When schools are attracted to food being dropped in the water you should be able to add vitamins and meds if they are also needed. You might even be able to lead them to a certain spot where processing is easier as they swim into the nets.
Just the upper lake alone could support a fishing industry of how many ton per year if Manitoba was to develop a food from grain. Roads around the lake would be needed to take over the transport of 'stuff' so there is a starting point for a 20 year project where the end result is an industry that feeds the locals and has enough left over to export. That supports 'newcomers' to the tune of a few million with lots of room for growth. All created by people others could not control as they were the stronger society. Isolationism in a global society is the same as protectionism, without fixing the problems associated the original version.
