Below is an excerpt from the EI website about when you can start maternity leave:
Maternity benefits
Maternity benefits are payable to the birth mother or surrogate mother for a maximum of
15 weeks. To receive maternity benefits you are required to have worked for
600 hours in
the last 52 weeks or since your last claim. You need to prove your pregnancy by signing a statement declaring the expected due or actual date of birth.
The mother can start collecting maternity benefits either up to 8 weeks before she is expected to give birth or at the week she gives birth. Maternity benefits can be collected within 17 weeks of the actual or expected week of birth,
whichever is later. Please note that the date you file your claim is very important in order for you to receive the maximum maternity benefits you are entitled to. If you are unsure about your most advantageous maternity period to receive maximum benefits, please contact us. If the actual date of birth is different from the expected date of birth, it is very important that you provide this date as soon as possible after the birth of your child. Please contact us at

Here is the website this was referenced from:
Employment Insurance (EI) and maternity, parental and sickness benefits
So, you can start your mat leave up to 8 weeks prior to your due date. Your employer is obligated to continue your benefits during your maternity leave.
As far as sick leave is concerned, companies are not allowed to discrminate against an employee due to a disability, which is technically what an illness could be perceived as. A best practice of most organizations is that they don't terminate people on sick leave- it would be a human rights nightmare.
Hope that helps. Does your company have an HR department? Usually they can be helpful. Also, you can always call the Service Canada 1-800#- they are very helpful.
