HR in Canada

Hi! i'm new to this forum board and i'm a mom hoping one of you could answer my questions.

I am quite knowlegable on the immigration process in Canada already but i need some extra info.

Do any of you happen to know the prospects of an HR generalist in Toronto, Calgary and Vancouver?

I've looked into the FSW program but the in demand 'list' has nothing in this field. Although i do have 10 years experience in noc 8222 supervisors in oil and gas but sadly the application requires it to be in the last ten years which it is not.

Would i be able to find a respectable paying job to support my four children in canada with noc 8222?

Finally, Which field is more available towards immigrants to Canada? As in which would i most likely be offered an LMO or AEO

Thanks for your help!
