The Canadian government did not remove the online directory. They changed its address to <https://apc-cap.ic.gc.ca/pls/apc_anon/query_amat_cs$.startup>. Be warned, it's not very fast.
+ It's also not searchable by an application like Pathfinder. The online version of Pathfinder is able to search the Canadian government's directory.
+ but the online version does not interoperate with DXLab applications.
