I was not able to find any answers for this question on the goverment website; so i thought if some would have encontered similar situation.
I got a job in canada after finishing my undergrade; but last week i got a better job offer. The problem is that on my permit goverment have specified my last employer and the city location. I know this can be changed; but "Do i have to wait till i get my another permit or i can start job with the new company in the mean time?" This company wants me to start the job right away.
