I suspect the United States will step in to support the People of Canada,, render protection and support,, help facilitate restoration of order and the formation of a new government... Greenland will be part of that picture,, probably become US Territory or a US Proxy at the very least,, the second Alaska,, protecting North America from the East and West...

What will happen to Mexico? Well currently they are part of the BRICS,, so likely good relations in the future under a Gold/Silver backed system,, both monetary and Technically...
