How much does sponsor need to have for international student?

[jatexgirl]

Hello everyone I am new to this forum. I would like to know how long and how easy is it to apply for a residency visa as an international student? I read somewhere that it is pretty easy to go from international student to resident. Also my sister is going to be sponsored by my aunt in Canada as an international student there, does anyone know how much money my aunt has to prove that she has, in order to be her sponsor? I read that she has to have $10,000 for tutition plus another $10,000 I gues for living expenses. All responses are appreciated.
