This represents a stunning about-face after years of public consultation on the whois policy. While the law enforcement exception appears to be narrowly tailored, the exception for trademark, copyright, and patent interests undermines a crucial part of the whois policy, namely compliance with Canadian privacy law (the policy now arguably violates the law) and the appropriate balance between privacy and access. For example, consider a Canadian that registers companysucks.ca (name your company) as a whistleblower site about a particular company. They understandably wish to remain anonymous to the general public since disclosure of their personal information could lead to negative repercussions. Under the new CIRA policy, if they use fake registrant information, they risk losing the domain. On the other hand, the backdoor exception means that the trademark holder can easily smoke out the identity of the registrant as CIRA will simply hand over this information.
Sounds like Geist is right.
