Canvec - the product supplied by NRCan to the general public - always
was split by feature type. It's the OSM tiles, of structure decided long
ago, that lump everything together.

It's also available as effectively seamless FGDBs if you want to avoid
the cleanup required after using tiled data. The FGDBs retain the
critically important survey dates and accuracies - so you can easily see
how much data's 40 years old and has ±75 m positional accuracy.
