There is no comparison, because in the U.K. individual suppliers are not party to the code. It focuses on the largest retailers and the largest suppliers.
In the Canadian context, I think this is logical. The trade associations potentially have a very important role to play in this and in representing their members, as you say, looking to systemic issues and bringing those forward to the adjudicator. In the U.K., the process of adjudication is a very light touch. There is no DRMP, dispute resolution mechanism. In the U.K., 99% of the issues are resolved through informal dialogue, often facilitated by the adjudicator, who would give an opinion and provide straight guidance way before having to be more heavy-handed.
