What is the best way across each province?

A few online resources to help with the scout:

Chatter from our forum:

The Great Trail (or Trans Canada Trail) is a good starter resource, but relies too heavily on asphalt and trails that are not conducive to cycling
Gravel Travel opens up some unique options but there is concern over too many long stretches without restock
West to east is the preferred direction of travel due to predominant winds

Questions

If we look at the route as also being a possible race, does it make sense to start on Vancouver Island or the mainland? Where is the ideal Grand Depart?
What if we head south down the island using Vik's route: https://vikapproved.wordpress.com/2015/06/27/vancouver-island-bikepacking-route/. Riders would fly from Vancouver to Port Hardy (5 flights / day). From there, take a water shuttle to Cape Scott: http://www.northcoasttrailshuttle.com/. Heading south down the island to the Nanaimo or Victoria to the ferry crossing > Tsawwassen, aligning riders with the BC Epic 1000 route, the best route into Alberta.
How do we get from Tsawwassen to the BC Epic? And do we swing north to Merritt or join Lennard's segment further along?
