It's perfectly legitimate for legislators to have a different view of high- versus low-impact AI. I think the point of the discussion is to try to make sure that the finite resources Canadian companies have are not used unnecessarily to do really complex assessments where they may not be necessary.
To give a bit more context to that, some risk assessments are actually in the millions of dollars to complete. They're very complex, and they require a lot of due diligence and information. Once you've completed that risk assessment, you likely want it audited by a third party in very high-risk use systems. That is not a small undertaking, especially for small companies and start-ups looking to start up their new business.
