Luckily there’s a lot more than the grocery rebate.
That said I hope these investments don’t go to the existing monopolies:
To help bring down the cost of groceries, which have been rising faster than inflation, Carney said he will direct $500 million from the government’s Strategic Response Fund to help food suppliers “expand capacity and increase productivity.”


Another reason I prefer to shop at the Co-Op. They have had unit pricing on their shelf labels for as long as I can remember.
Add that to the fact that they prioritize local and regional product (and identify that on shelf labels as well), and that the profits stay local, rather than going to some international behemoth, and there is very little reason to go elsewhere.
I wouldn’t shop elsewhere if there was a co-op around. There’s a farmer’s market near me during the summer and we frequent that.
