hi there,
if your temporary resident visa is still valid then you dont have any prob with that..if it is already
expired, you need to apply for re entry visa at the canadian embassy in manila, be sure to have a letter
from your employer, that theyre expecting you to comeback.I, myself will also do the same , ill have my vacation next week.
you can get all the info and the docs. neede at their website.
www.philippines.gc.ca we are under the link returning foreign worker.
goodluck.
