There was always a risk your parents would not be able to get TRVs so you need to plan in case they aren’t able to visit Canada. You are present so your wife is not alone and you can help with cooking, cleaning, laundry, shopping, anything related to the baby except breastfeeding, etc. Supervisa is based on income earned not salary which is why NOA is typically the only evidence accepted by IRCC.
With that income, perhaps they can hire someone to take care of the cooking, cleaning, laundry, shopping, anything related to the baby (instead of the husband doing so).
