Blind people don't necessarily need to read the signs. If they're in a city like Toronto, they already know there are cross walk signals at all major intersections, and these always have buttons, and the buttons are almost always in the same spot (especially with newer signals, where the buttons are mounted on short posts immediately beside the tactile strips, rather than on the main post holding up the overhead signals). If I recall the signs do have Braille text, but even if they didn't it wouldn't really matter, would it? Either way they'll need to push the button.
