Canada's privacy commissioner announced Wednesday that she has completed her formal investigation into Facebook in the wake of the company's recent privacy policy updates.

The social-networking site is not completely free of the commission, however, as it will continue to monitor Facebook features, including the "Like" button.

"The changes Facebook has put in place in response to concerns we raised as part of our investigation last year are reasonable and meet the expectations set out under Canadian privacy law," Commissioner Jennifer Stoddart said in a statement. "The issues related to the investigation have been resolved to my satisfaction"

Stoddart has been working with Facebook since August, when an inquiry from her office prompted Facebook and embark on a year-long overhaul of its developer platform. In January, she announced that her office was examining online tracking, profiling, and targeting of consumers by businesses  including sites like Facebook.

In May, Facebook that provided a one-stop shop for selecting privacy settings, made less information publicly available, set controls for Pages, and allowed users to opt-out of third-party applications.

Stoddart said she is "pleased that Facebook has developed simplified privacy settings and has implemented a tool that allows users to apply a privacy setting to each photo or comment they post."

In June, Facebook that explained what type of information Facebook apps were gathering from users. Third-party apps were a major concern to Stoddart, she said Wednesday. Specifically, her office was concerned that third-party developers had "virtually unrestricted access to Facebook users' personal information."

Adding this permissions-based menu "is a vast improvement," she said.

"Giving people control over their information has always been a priority for Facebook and we appreciate the dialog we've had with the [Office of the Privacy Commissioner] to clarify and enhance our privacy practices," Michael Richter, Facebook's chief privacy counsel, said in a statement. "Both Facebook and the OPC share the same goal of ensuring that everyone, including the more than 15 million people using Facebook in Canada, have control over their information."

Despite concluding her investigation, Stoddart said her work with Facebook "is not over." The commission has asked the social-networking site to improve its oversight of app developers and make sure they are informed about their privacy responsibilities. OPC also warned Facebook not to expand the categories of user information it makes publicly available.

Stoddart said her office has also received some new complaints relating to Facebook's invitation feature and its "Like" button.

"Facebook is constantly evolving and we are actively following the changes there  as well as on other social networking sites," she said. "We will take action if we feel there are potential new violations of Canadian privacy law."

Nonetheless, Stoddart praised Facebook for its cooperation, and acknowledged that some of the changes were "complex and time consuming."

"Making the privacy controls on Facebook comprehensive and easy to understand is an important part of our commitment to giving every person the power to control their own Facebook experience, and will continue to be even though this investigation by the OPC has been concluded," Facebook's Richter concluded.
