The boundary symbol library previously contained 13 lines, 10 of which were dominated by a grey backer. The intent was to make boundary classes explicit, but with this came a complexity which was difficult to penetrate. In CanTopo, boundary classes are abandoned in favour of giving voice to boundary types: geographic, administrative and recreational. Now, rather that wrestling with what a boundary class means, the map reader may now know, at a glance, the boundary type and, by extension, the land contained within.
