Since my initial post that Campbell's has inaccurate "prepared in Canada" packaging, a few people have been countering with this CBC article - https://www.cbc.ca/news/canada/windsor/buying-canadian-trade-war-freshco-1.7475613
This CBC article is only situationally accurate.
There are different versions of Campbell's packaging. Some say "designed in Canada". Some say "prepared in Canada". Some say nothing. Some list the address as Mississauga, some as Toronto.
I don't make claims without receipts ;)
