I still don't see how this wouldn't be considered working the system and somewhat shady. You're going to live in Canada and maintain residency there. Unless you'll be handling all of your tax, ei and cpp premiums yourself why would payroll go through the extra steps of submitting your pay from a USD payroll to Canada Revenue Agency?

Also, if your taxes and deductions are going to be made to a State or Federal government then you aren't contributing to Canada. You're not contributing to our health care system and social programs. So, basically, you'd be the guy on Canada's couch who contributes nothing to the household.

Make no mistake. You are trying to cheat the system. You are trying to get an advantage in order to make financial gains. Stop trying to justify it to everyone by going "it might not be illegal, guys". Legality and ethics do not always match perfectly.
