Hm, not too much, you'll have to read all the requirements for all the different documentation.
In general, you need certain residence and other requirements in the province you live in to submit all the paperwork for a change of name. After you do that, you can get a new birth certificate from the province where you were born, then use that for a new drivers license, then use those to get your name changed everywhere else.
