Hi, I have an Employer-Specific work permit for a year, I have already 6 months on but the owners are decided sell and finish the business. I found a new job offer to change my employer application but, this new employer need to submit my offer at the Employer Portal again for the number? He need to pay for me $230 again or if the time of my old work permit is still valid is not necessary and with the contract signed and +LMIA is enough ?
