Are Hatt Street, York Street, and York Road accurately mapped as highway=secondary? Are they as important or have as much traffic as Governors Road or Osler Drive? Are John Street, McMurray Street, and Foundry Street highway=tertiary?

Looking at these on the map and on aerial imagery, I am tempted to downgrade them by one rung (making Hatt/York tertiary, John/McMurray/Foundry unclassified), but I'm not familiar with the area in person. What do others think?
