I'm not sure what you are not understanding. Unless you marry a Canadian citizen or PR or find a way to immigrate on your own (skill or student or have a shed load of money to invest) you are NOT eligible to come to Canada. Your brother, cousin, uncle, etc CANNOT sponsor you now or likely ever. So, in plain English, the only way you are moving to Canada is if you:
1) Marry a Canadian citizen or PR
2) Qualify for a PR visa with your skills and experience
3) Have enough money to pay for a higher education program (college or university) or
4) Have enough money to invest in Canada
I would suggest you read the CIC website to see whether there's a visa out there for you that you meet the eligibility criteria for. In the meantime there is no sense in beating a dead horse! You're not coming to Canada by being sponsored by your family any time soon.
