Personally, I think that you are setting yourself up for big problems..
I don't think that a Hungarian passport will get you through the border without some serious questions. CBSA are well trained, especially in detecting "red flags" in someone's profile. My guess is that if you try what you are planning, you will never even get past secondary inspection. If that happens, no lawyer will be able to help you.
Also, because you do have dual nationality, you can forget about asylum or refugee status, because you always have an alternative country of citizenship to flee to.
