Nutritional Panels for Canada and the US requirements are different.
We also need to have both languages in English and French on the Canadian and US Package. ( If you plan to sell it in both countries)
Canada Date Code format (Canada: Best before/Meilleur avant: 2007 JN 05) is also different than the US one (Best Before/Best By: NOV/21/2021)
The way to do it is to print the actual package for the main customer which I believe is in Canadian Format.
Then you can develop those nutritional panel and ingredient list stickers in US format and label it on the actual package.
I'm looking forward to hear from other people advice on this topic as well.
Hope it helps!
