For an exemption process in Canada to have effect, it would first of all have to enable the circulation of circumvention tools, and that's not currently available in the United States.
The second is that under section 41.21 we could essentially have a panel of experts, an administrative body, that would review certain implementations of TPMs and exempt them from protection where they impede certain conduct or acts that we think are in the public interest—repair being one of them.
This would offer a number of benefits, because it would be more responsive. We wouldn't be worried, for example, that the mod chips would be under the auspices of repair, because we would be looking at the implementation of TPMs in specific devices and products with the necessary technical expertise and would be judging that implementation on its connection to copyright.
