If you are coming here to work on an expat package your employer will sort everything out for you if you or your wife dies. I presume you assets will still be in Canada so no you dont need a will here for you Canadian assets. On another note, my english friends father died and was buried here, (christian) and the buriels are done the same day or at least within 24 hrs, no church service etc, straight to the grave yard, no prayers at the graveside.
