Canadian province Alberta will ban schools from promoting political viewpoints. Bill 25, tabled in parliament this week, prohibits teachers and school boards from commenting on societal and ideological issues.

The bill targets what provincial politicians view as 'activism' in education. Schools cannot display flags or symbols from non-government sources under the law.

Supporters say schools must focus on teaching. Teachers should not share personal political opinions in the classroom, they argue.

Opponents warn the proposal restricts freedom of expression. They fear topics like human rights and equality will be excluded from schools.

The bill remains on parliament's agenda. The voting date is currently unclear.
