Just underneath that picture it says it was not implemented.

In 2013, a minority PQ government proposed the notorious "charter of Quebec values," aiming to ban religious symbols for public servants, but it went nowhere after the PQ lost the 2014 election.

The bill is still being debated in the supreme court. A timeline with more details and updates can be found here: https://ccla.org/major-cases-and-reports/bill-21/

That said, the Quebec government has been pretty fucking hostile to people who wear religious symbols. The original article frames it as residual tensions from the French Catholic chuch but a big part of it is definitely xenophobia and racism. Montreal and Quebec City are progressive havens in a land of very small, very white, very religious towns.

Again, i don't really care, i'm providing context you purposely left out.
