What is incredibly difficult to find is un homogenized milk in bags, here in Canada (Toronto GTA). Most stores don't carry un homogenized milk at all. The only available option is organic milk in 1 l glass bottles. But, the price might be prohibitive for lower incomes. I prefer un filtered milk, but I only buy the glass bottle in summer as it is grass fed, and even then, I still buy organic whole milk bags (3.8%) for my milk addicted family.
