Road access in B.C. gets complex at times.
Generally speaking, logging roads that were constructed from scratch by private logging companies, using their own funds (even logging companies who may have sold their assets down the line to other companies) are deemed to be owned and controlled by the logging companies. These are often called "logging roads", or "industrial roads" ... but that nomenclature doesn't always assign the publics rights, or lack of rights to access the roads.
Logging companies who privately own land on which roads are located, IF those roads date back to the 1800's or early 1900's, and were once a public transport route, must provide continued access on those roads, which in non-legalese have technically "always" been publicly used roads constructed the Crown, with the land only sold (or given) in later years to private logging companies.
In reality, logging companies (like Timberwest, now disguised as Mosaic) abuse this continually, often forcing folks with a legal right to use roads constructed in the 1800's or early 1900's to go to the courts to get access that is legally theirs (placer miners, sports fisherman fishing publicly owned lakes, First Nations for hunting and salal gathering, etc).
Locally (as an example), the Boneyard Main in Sooke is argued by Timberwest and CRD Water to be on private land, and is indeed gated off in multiple locations. There is an ongoing argument that in fact, the Boneyard Main is an 1800's public transport road that pre-dates any logging company ownership, a road that was originally built by the Crown to provide placer mining access to the Leech River, and further was used as a public access road for decades before it was gated of in the early 80's.
A similar argument is currently being played out on the Douglas Lake Cattle Company lands, whereby the ranch is trying to prevent access to publicly owned lakes, by gating roads that have been in place in some cases for over 150 years ... roads that were built by B.C. pioneers (or the Crown), but which now transit privately owned Douglas Lake Ranch land.
The basic concept is that any road constructed with Crown money (which is public tax money), even a road that was constructed in 1895 ... remains a public road as it was constructed with public funds, and with the publics best interest in mind.
And many logging roads, and industrial roads in B.C., regardless of land ownership, are, in fact, historic transport roads transiting difficult to access areas of the Province, and were (and still are) integral to the ongoing benefit of citizens of British Columbia who wish to access Crown lands on (in some cases) 130 year old roads that were built with their ancestors tax dollars.
