As Canada is still part of the commonwealth you would have the full backing and support of all commonwealth countries.
New Zealand will send over their peace keeping forces to help rebuild bridges, schools dig new wells and hand out chocolate bars to the refugee american children. While the SAS will secretly parachute into the rockies from which they will spend their time fishing , hunting deer and drinking while sending faked radio messages on american terrorist movements.
India ( I know there not part of the commonwealth anymore but once they hear of this opportunity they will fall over themselves to rejoin ) will send out troops who will immediately desert and open up restaurants and small shopping markets.
The australians will all get drunk then go and enlist. From there they will be sent to Cairo for three months intensive training and a huge pissup. Then they will all be put on boats and get so drunk that they will end up landing on the wrong beach and iimmediately invade the first bar they come across and get horribly drunk.
And the English will send over troops to get the back the taxes plus interest owed on the tea.
