My experience at canadian high commision residence was really amazing one, we had a meeting organized by the commision to introduce edu_canada. The residence is at oysterbay area which is one of the coolest zones in Dar, just after the coco beach(famous huge public beach). Well built nice buildings and color as well as the security system. And one more amazing stuff is it has a very huge parking area which can accomodate alot of cars. So dont worry your car will be safe.
Cool
