Most western countries? I find the produce, especially if it's in season, is much cheaper than the produce in Canada, and it's fresher too. Food in the United States is ridiculously inexpensive.
Price of fresh produce in the US varies depending on where you are. In many places, using the phrase "ridiculously inexpensive" would get you laughed at and/or castigated.
That said, fresh produce in the US sucks. Every European country I've visited has had notably better produce. I had a garden salad in Italy that actually made me pause and go, "Oh, these aren't supposed to be a form of self-flagellation in the name of health. These is actually delicious food." I rarely have that experience with US produce.
I lived in many European countries and all are cheaper. Same for the US. Canada might be an exception but the time I spent there (Vancouver), produce was cheaper than Japan (I live in Osaka).
