Daycare worries are not unique to  French Language schools. The challenges were the same  years ago for us in Richmond,  when  capacity schools resulted in no spare space for childcare.

And enough with the  "permanent loss of these services and long-term degradation of Vancouver as a city welcoming multilingual/multicultural immigration."  Richmond's demographics are approx 65% Chinese  - does that automatically mean any cutbacks anywhere affect our multicultural image?   

I recall for a couple of years daycare had to be housed in a portable on our neighbourhood school grounds - perhaps this is an option for these schools?

The challenge is parents advocate for change usually only when it affect them.  If enough parents continue to protest, especially when electing school trustees, or politicians at the provincial level, perhaps more would be done. 

And if parents and taxpayers are willing to pay additional school taxes for infrastructure, then facilities will get built.
