Depends on the length of time granted you at your port of entry. If it is co terminus with your visa then you must leave by that date, but normally the poe officer grants a WP equivalent to the length of time specified on your work contract. The visa validity is the time when you can enter Canada, the latest date being July 15.
I have just received my canadian W-1 work Visa whose validity is from 1st May 2011 to 15th July 2011.. These are also my employment dates. I have got a multiple entry Visa. though i'll enter canada once around 6th May, but as my employment ends on 15th july, i have to leave canda after that i.e around 16th July as there r no evening flights to INDIA on 15th( i am a citizen of india). Now what should i do.. my transit is through frankfurt which wont let me transit without a valid visa..
is it ok to leave canada after visa expiry
