Canadian province Alberta will ban schools from promoting political positions. Bill 25, submitted to parliament this week, forbids teachers and school boards from expressing opinions on social and ideological issues.

The bill targets what provincial politicians see as 'activism' in education. Schools may not display flags or symbols not from the government.

Supporters say schools must focus on education. Teachers should not share personal political opinions in class, they argue.

Opponents warn the bill limits freedom of speech. They fear topics like human rights and equality must stay outside schools.

The law is still on parliament's agenda. It is unclear when voting will happen.
