Hi everyone, i am an open work permit status and waiting for my pr approval , i just comeback from vacation and i just want to share with you what the lady border officer at the Toronto Pearson International Airport told me about this letter of employment that some of our fellow foreign workers are saying that it is needed or a requirement before you enter canada,i ask the the lady border officer if it is really necessary for me to show to her my letter of employment from my employer and same with other foreign workers inspite of having a valid work permit ,and she answered me very politely that THEY DON'T NEED ANYTHING EXCEPT FOR THE PASSPORT, RE-ENTRY VISA,EMBARKATION CARD,AIRLINE BOARDING PASS NUMBER AND VALID WORKING PERMIT! i do hope that this would enlighten everybody that are planning to go out of Canada for vacation.
