I pay into EI for self employed. I haven't used it but it would be the same as collecting mat leave from before. You get an amount based on what your income was (after deductions). The thing is you have to pay into it for a full year before you can apply for EI benefits. The max it costs a year is around $800. I think I only pay around $300-$400 a year to pay into it. I pay into it mainly in case I get sick and can't work but it covers mat leave too. Why not pay into EI and save up some money in case people back out on you again.
