I too would like to see how they're doing several months from now. Winters there can see temperatures dipping to the -40's,
plus wind chill. And the wind does blow at times on the prairies

.
I wish more details would have been provided, such as where they're getting water, how far from the nearest town to resupply, what sort of toilet facilities and so on. They will be needing a lot more clothing than whats on their backs when winter arrives.
There is no chance that they're actually walking across Canada with all that gear, or that they're self sufficient. It's simply not possible given their location and circumstances.
I'm going to assume that the local people have provided them with much of what they have and their success depends entirely on the goodwill and charity of those people.
This story is being talked about here. Not one person believes that they'll make it through the winter. Everyone is in agreement that they will fail, simply because knowing how brutal the winters can be. I hope they prove all of us naysayers wrong.

I would also like to know where in Ontario they came from, because it does have a direct bearing on their chances of success. If they came from southern Ontario, the temperatures are much milder than those experienced in the west or north.
I wish them well but think they are very naive to say the least.
