I live in Vancouver, the cost of living can be quite high if you are living right downtown, but it's not too bad if you live in the suburbs. As for safety issues, it is pretty safe here but the downtown eastside area of the city should be avoided. What university are you applying to, UBC or SFU? Vancouver is a beautiful city, with the ocean and mountains both nearby. Keep in mind that it rains here a lot though. If you have any more questions let me know.
