Several US Airlines are already making it easy for Canadians to work in the USA. There are stories getting around about United issuing greencards to Canadians and companies like Horizon and CE dropping their citizenship requirement.
Oh and if you want to get a job in AUstralia... easy.. just go to Indonesia and rent a fishing boat and sail across. Even if they catch you you will receive a financial aid package as a refugee that is higher then what we pay our Vietnam Vets and their widows!! You will receive free legal aid in order to apply for permanent residency and be housed for up to a year or so while this goes on. :-)
