Transparency could indeed be improved. There are a lot of challenges relating to the confidentiality of certain data concerning the various credits given by certain issuers.
I do understand though that it's a question of competitiveness. There are nonetheless ways to share this data confidentially so that independent researchers can look at the effectiveness of the system, for example through Statistics Canada and a pan-Canadian network of data research centres.
In my opinion, we could have higher accountability requirements for companies, which could provide that confidential data to the research community.
