well that depends on the damage, as well as the technician you hire. you can hire a professional technician, with a large background in electronics, who will likely take a benching fee for the time and effort. if its a broken screen, you can usually look around 90$CAD - 140$ CAD for off brand devices, but can get higher depending on cost of part.
essentially, you should call around your local repair shops to see what they will charge, because costs vary so much
