One reason I want to get out of here.... power failure for a few days in winter ... local municipality is handing out $100 gift cards to all too dumb to put their food outside... I get to pay for it.
I see your point, Roy. In my case, we've got containers I could bury in the snow even if our air temps are only down to the freezing point or just a little above. So food could be stored in these for a while. Our friend who asked for freezer space likely does not have any containers that would work for that. Containers would be valuable, to keep the food items consolidated and maybe give a bit of protection against roving neighborhood dogs that might like to dig food up at night.
Containers here would have to be buried deep enough that the thawing process of the snow here would not soon uncover them. Whereas I assume your winter temps in Ontario would maintain the snow depth better.
As a shorter-term stopgap method, we keep blankets in our basement right next to where our two freezers are. When power goes out, we cover the freezers for added insulation.
