Organic Soy Wax
Willow Earth's homemade ethical & vegan-friendly soy wax is made from 100% organic soy and alongside many other purposes can be used to help improve the water-resistance of canvas backpacks.
One cube is enough for two layers on one rucksack with plenty left over for anything else you fancy waterproofing.
You can see instructions on how to do it here.
