Great find!

I didn't know that :)

Good thing for OSM Local mappers to fix it, i'd say :)

Use the GeoBase WMS layer
http://wms.cits.rncan.gc.ca/cgi/wms_en.cgi?map=/export/wms/mapfiles/rhn/geobase_rhn.map&version=1.1.1&service=WMS&request=Getmap&layer=HYDRO_AGGREGAT&format=image/png&STYLE=default&layers=GEOBASE_RHN_NHN&

 and the Toporama WMS layer
http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?LAYERS=limits,vegetation,builtup_areas,designated_areas,hydrography,hypsography,water_saturated_soils,landforms,constructions,water_features,road_network,railway,populated_places,structures,power_network,feature_names&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application/vnd.ogc.se_inimage&FORMAT=image/png&

(im now working on getting CanTopo_geo.pdf maps convtered to WMS via MapWarper.

Also, YanMorin has created the linear network flow for all of Canada
as .osm files,
http://osm.progysm.com/rncan/geobase/nhn_rhn/
and it includes the oneway=yes with proper direction arrows, as well
as proper geometry (for BC basin) and river names where available :)
