Canada's new anti-spam law matches all the requirements of the US can-spam law, but goes a step further in that it requires prior consent from the recipient. In the case of sending an email to a person in the US, the default is that the person is opted-in -- and must be presented specific means and information to opt-out. Listen360 already complies with these rules.
In the case of Canada, it is assumed that any recipient is opted-out, and must explicitly opt-in. So if you have Canadian customers, you should be collecting email addresses directly and not pulling them in some automated fashion (such as purchased lists, etc.). However, there is language which exempts explicit consent when there is a business relationship in place -- including a purchase. That purchase in turn gives implicit consent for email contact for the following 24 months.
This means that companies using Listen360 will comply with the law as it pertains to the feedback process, but care should be exercised when using purchased lists for any marketing activity that include Canadian recipients. This is ok for the US but can no longer be done for Canada (starting July 2014).
