How do other regions in Canada understand the issue your article explains?
Other regions in Canada might understand the issue of having a french word in your company name because almost 20% of Canada is French and a lot of the population will disagree with this new regulation that they want to introduce.
How can marketers use this article to be more successful at selling products?
Marketers that are in Quebec can maybe implement something French in their company name but I do not reccommend doing this if you are not based in Quebec. Although there are some exceptions like for example HomeSense or Roots.
