I meant I've read on the official website that my mother can't sponsor me because of my age. I thought age is not important.
Of course I knew overstaying isn't illegal.
I wouldn't stay in Canada working as a damn laborer without hope I may get permanent resident.
qwertypod, want to make impression you're smart guy, psychologist?
I'm wonder, based on what you've decided I'd try to break the law and try to overstay at all cost? I guess I have to be some bum or something like this.
You say you know overstaying
isn't illegal? Is that a typo and you mean to say you know it IS illegal?
The thing is, overstaying really won't lead to Permanent Residency even if your Mom becomes a citizen. The only way that you can get PR (and I'm sure you have considered this) if you happen to marry a Canadian citizen and they are willing to sponsor you. Even then, IRCC is extremely suspicious of relationships that begin this way and there are many cases of applicants being denied because IRCC believed that the marriage was only done for immigration purposes.
Also, if you get PR under false pretenses/misrepresentation, it most certainly is an impediment to future citizenship/PR card renewals. IRCC can (by law) even cancel your citizenship if they ever find out your came in fraudulently.
Living as an illegal alien isn't easy, as you point out. Not only will you not be able to find highly-skilled work, you also wont' get healthcare and will not be able to leave Canada to travel.
You're young, have you really looked at all your legal options for immigrating? I'm not castigating you, but if you post your full situation and profile we may be able to point out better options.
