Reference your e-mail concerning immigration to Canada and sponsering you. Please check the following information on ; www.cic.gc.ca , this wb site from the canadian goverment should answer your queeries !
Unfortunatly , I am not legally allowed to sponsor a person who isn't part of my family ! You must find out where you would like to establish yourself. As for teaching commercial diving, you should enquire if any commercial diving schools need a extra hand.
You might want to remove your personal email address from your post. You are just asking to be heavily spammed.
