I don't know how much better it is but I've been mostly patronizing my local Food Basics, with the occasional trip to Walmart and Costco for things they don't carry at FB. I avoid the Loblaws' chains after it became obvious they were doing the biggest price-hikes to drive inflation while Food Basics was raising wages and giving more of their employees full-time benefits.

I realize that Walmart is ethically a damned sight worse, but one battle at a time. Walmart doesn't give a shit what their Canadian customer-base does they're a global company. Loblaws lives and dies by it.
