Canadian province Alberta will ban schools from promoting political positions. Bill 25, introduced in parliament this week, bans teachers and school boards from expressing views on social and ideological issues.

The bill targets what provincial politicians see as 'activism' in education. Schools cannot hang flags or symbols that are not government-issued.

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

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

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