I had a look at the bill in question, bill C-273. It proposes to define "technical information" as a "product" under section 75 of the Competition Act. Section 75 falls under the heading of "Restrictive Trade Practices" and specifically "Refusal to Deal".
From the Competition Act:
If I understand this correctly, the bill aims to prevent motor vehicle manufacturers from refusing to sell a product, namely the technical information needed to "repair, service, and diagnose" a motor vehicle, to motor vehicle owners and independent repair shops, because that would "substantially" affect the independent's business or even preclude them from carrying on their business, and that would have an adverse effect on competition in the market.
The actual "Right to Repair" part of the bill comes in the form of an amendment to the Canadian Environmental Protection Act:
Section 153 concerns emissions standards compliance. The bill also includes provisions for regulating fees and how the information is provided.
