Not sure this also covers your car.
It seems not only your CV joint boot is broken, but also the CV joint itself. If it's only the boot, you can put a split version on yourself for ~$10 (guess that's not an option for you).
If your left front tire is leaking, then there is no way to repair it; you have to change one. I don't understand why police will fine you if your tire is not good enough. Are you really in Canada and the law is different there. Anyone knows why?
