Without knowing your end goal, you might have luck with the Vegetation Resource Index polygon layer available from the DataBC Catalogue.
The VRI is:
Geospatial forest inventory dataset updated for depletions, such as harvesting, and projected annually for growth. Sample attributes in this dataset include: age, species, volume, height.
The Vegetation Resources Inventory (VRI) determines both where a resource is located and how much of a given vegetation resource (for example, timber or coarse woody debris) is within an inventory unit.
So, it's a land cover map that focuses on vegetation, but also provides a lot of extra attribute information.
