Am I starting mat leave too late? [ca]

FTM in Ontario working a corporate job. I just had a chat with HR about when I plan to start mat leave but now I am having second thoughts.

I’m due April 2 and my last of day will be March 18 (I will be 38 weeks). Then I’ll use my 5 days vacation and officially start mat leave on March 25.

My plan has always been to stop working 2 weeks before my due date but now I’m like: what if he comes earlier? I would really like to slow down, rest, get together all the last minute things.

I should add I will be commuting to the office only once a week in February and I will be fully remote in March. Aside from my commute on the Go train, I spend my 9-5 working away at my desk.

What would you do?
