UIF - Unemployment Insurance Fund - Balance

I have been employed for over 22 yrs,never claimed UIF benefits before because I never lost my job before. my last job was a contract job and after the contract has expired I applied for UIF and started receiving it.I need to find out how long I am supposed to receive it and how much in total for the years I have worked because only after a few months of receiving it I am now told my contribution is depleted.Pls assist me in finding out how much my contribution was and how much was liable to me
