Milk is a bodily secretion, so I expect there is at least a chance of pus in the most organic, grass-fed, free range milk you could imagine. Maybe Canada's limits are higher than others, but you're not going to get to 0%.
It reminds me of people surprized that food companies are "allowed" to have insect parts in their food. Actually, you WILL have insect parts in your food, what the law does is specify a limit.
