That's a problem, because I have no idea what these products might be called in Canada. Turface is calcined (baked at high temperatures) clay, and crushed granite is often sold as chicken grit, but it's important that you don't use a grit made with shellfish as a part of its make up.

In this picture, the tan material is screened Turface and the white material is crushed granite - chicken grit in grower size.
