It all depends on for how long your are baned from Canada. There are different "deparations" (or what ever the correct terminoligy is). If you were simply sent back to your country of origin, banned from entering Canada for a few years - or banned for life (which I doubt in your case). If you were only sent back or baned for 3 years, yes you should be able to apply for a visit visa and return.
so if i didnt baned for life from Canada, i can enter without any problems and without paying any fees?
where i can ask if i baned for life or no, can someone give me email or tel where i can ask?
Thanks for your help!
