I think that standard construction has tended to ignore cold corner problems, because corners are often stacked 2x4 which have an R-value of about 1 per inch. So you end up with a large area that has a low R-value, and insulation can't reach it.
But you should still try to reduce infiltration as much as possible, inside & outside. Foam from a can is a good way to go. You might be in a bit of a quandary at this time of year, because the temperature is so low, that the foam might not expand to it's full potential.

As a side note, I'm in the process of remodeling and insulating my back room, and when I removed inside window trim, I found torn bits of clothing that desperately cold people had jammed into the cracks and gaps around the window over 100 years ago.
Our quest for warmth is an ancient one.
