The CRD resource map agrees that West Saanich Road, up to here and continuing all the way into the Tsartlip First Nation to the north, is a bike path. 

However, unlike the district of Saanich's document, CRD's map clarifies that this class of bike lane is either a dedicated bike lane, OR a paved hard shoulder that is maintained enough to cycle on without sharing road space with cars.

Aerial imagery from 2023 supports this interpretation: West Saanich Road has fairly wide paved hard shoulders in both directions, definitely usable as cycle lanes without having to fight cars for road space.

I'm not sure how OSM normally represents this "not quite a full bike lane, but definitely built out with cyclists in mind" type of roadway.
