Bonjour, la meilleure source d'information de l'immigration canadienne est le site IRCC https://www.canada.ca/fr/immigration-refugies-citoyennete/services/immigrer-canada.html
It's not that hopeless. There's not so much agism in Canada for tech positions in particular. And for the express entry you can be selected as well despite the age. I know that for sure from my own experience.
Nobody can just apply for a work visa. You need to find an employer that would want to hassle with your work permit and LMIA.
You can apply for EE with your French, you have a good chance.
