Yes, there is a risk, but I think it is being managed properly, more or less.
The definition could probably be narrower but then national security agencies, such as CSIS, would be deprived of the information they need for their work. However, there is a risk. How can the risk be reduced? The answer is through independent and effective review mechanisms.
The part of Bill C-59 that deals with CSIS has a number of filters exercised by independent members of the executive of the government and the Canadian Security Intelligence Service based on high standards, including necessity. Overall, I think it's a fair balance.
