We all know Service Canada is ridiculous to get ahold of … so I thought I'd ask here.
For those of you who have taken sick leave or looked into it - do you have to take it right away when receiving medical approval? Or can you delay it until you've worked out notice and decided when the best time to begin the leave? I really want to avoid starting Mat Leave 8 weeks early so I don't reduce the time when LO arrives at the end of Mat Leave. I just want to have all my ducks in a row before I decide to officially leave work early as I am seriously contemplating it.
Thoughts? Thank you

Re: CDN Mamas - Sick Leave and EI
If I don't get enough supply days in before May, I could go off a few weeks early so that they'd count more of my hours from last year but I don't know if they'd allow leave to start before the actual EDD/delivery date.
Sorry, I know that's not helpful for your situation but I am also really curious about the answers you get.
So confusing!
I've called for the past couple days and 1) my call was dropped 2) they say they can't put me in the wait bc so many calls or 3) it's a 45 min wait to be talked to!
I never had this issue before but meh what can I do? Gonna try yet again first thing tomorrow morning!!
The 15 weeks prior to the delivery does not affect the amount of maternity/parental leave you are able to take (15 weeks maternity/35 weeks parental for 50 weeks total) so you could have up to 65 weeks of EI.
Regular maternity leave can start 8 weeks prior to the EDD, but if you don't qualify for sick EI, then you have to go back to work earlier.
