employment history checks
 

say u got fired from one of ur pervious jobs. is there a way employers can find that information if you dont mention that u ever worked for that company on your resume? like some online site or government database that gives u all this information with your SIN or something?

not really. besides, there is a rule or law that a current employer, interviewer cannot call any previous jobs you have if you did not give them as reference. Usually when u fill out an application there's a section where u put ur top 3 references. what you put there is the only ones they can contact.
