"Another important manufacturing hub for Finish dishwasher detergent is in the United States. With a growing market in North America, the brand established a production facility in Chesapeake, Virginia. This U.S. manufacturing plant caters not only to domestic demand but also exports its products to other countries across the Americas."
At the end I didnt find a Canadian detergent in powder, but I found one in tablets from a brand named "TruEarth" and another one from the "Unscented Company". That will have to do until I can find one in powder.
Edit: Thank you all for the recommendations, I will let you know how the truearth tablets work for me and after that I will probably give a try to nellies :)
Damn! I had high hopes they were good across the board. It’s so hard to find simple dishwashing powder anymore. Everyone’s fallen hard for the dissolving pod bandwagon.
