The censured her:

The Doug Ford government has put forward a motion that would censure an Ontario NDP MPP over her comments on the Israel-Gaza war and ask they not be recognized in the legislature until a formal apology is made and a statement on social media is deleted.

The motion calls comments made by Hamilton Centre MPP Sarah Jama last week “antisemitic” and “discriminatory.” If passed, it would call on the Speaker not to recognize Jama in the House “until the Member retracts and deletes her statement on social media and makes an apology in her place in the House.”

So they're trying to completely take away her ability to govern because of her speech. So yes, the government is trying to silence her.
