Carney needs to create favorable conditions for Aldi (a German company) to enter the Canadian market. They already have a strong presence in the north eastern US and they could easily undercut the existing Canadian grocery monopolies. This is a market in desperate need for healthy competition.

Costco already undercuts Canadian grocers. Most Canadians that have one available preferentially go there but it's not enough. If the Canadian grocery market is bloated and inefficient, letting more light and agile (albeit foreign) players in will be a much needed wake up call for domestic corporations.

This is not advocacy to remove all red tape in retail. Target tried to break into the Canadian market and failed miserably because they couldn't adapt to Canada. In my view that's perfectly fine, but Canadians desperately need relief when it comes to cost of food and its unlikely that will come from their grocery oligopoly.
