Hello Cherti,
Thanks for a very informative guidance.
I have one confusion regarding schooling. On one of the blog i read that kids of WP holders are considered temporary residents and get some exemptions from French learning in public schools.
The post mentioned that the child is given English medium of instruction for 2 years(WP expiry) for main subjects and French is taught as second language. Additionally, history subject is taught in French.
After WP, if one receives PR status, complete education medium becomes French.
Pardon me if my knowledge is incorrect. If someone can throw light on this issue, it will be helpful.
