Hey Ghufran,
I am in similar situation and I looked into this. I do not think you can do that. That would apply if you are only visiting the US. See this (Taken from CIC website):
Expired Temporary Resident Visa
- You can ask to come back to Canada on your original temporary resident visa, even if it is expired, if:
- you will only visit the U.S. or St. Pierre and Miquelon, and
- you will return to Canada before the end of your approved stay in Canada.
An officer will make sure you meet all the requirements before allowing you to come back to Canada. If you visit any country other than those listed above, you will need a new temporary resident visa.
