For wilderness canoeists, topographic maps are indispensable, and not replaceable by electronic systems. There are no electrical outlets in the wilderness, lugging batteries across 3km portages isn't an option, and canoe trips can easily last two or three weeks.
Fortunately, they don't currently have plans to stop. However, the Canadian government has recently added a list of Certified Map Printers in addition to the older network of Map Dealers who carry the entire series of thousands of maps (but frequently run out of the map you're looking for). Presumably, Certified Map Printers will print maps on demand. Sounds great!
Incidentally, you can also download Canadian topographic maps for free, and print them out yourself. But going into the wilderness with maps that aren't waterproof would be tantamount to suicide.
I wonder if the UKHO has made similar provisions to refer customers to print shops that have the equipment to print waterproof charts on demand.
