The law says you can't acquire or import real looking fake guns, though possession and use are ok. But people have non-clear guns anyways, because the enforcement of the law is rather relaxed aside from importation and retailing. CBSA is generally strict about importation, police are generally less strict about acquisition.
So, even though the law says it should be clear, no one has really gotten in trouble with non-clear guns unless they did something stupid or import related.
