I've had a question / request for the National Survey of Student Engagement which is not a Statistic Canada survey:
Does anyone know anything about acquiring results, preferably the most recent. (2014 survey year?)
The NSSE is administered for Canada and the US by Indiana University Bloomington. They administer the survey for the US and Canada, and this is where MacLean’s got the data from for the article that you included in your message.
You can poke around their website to find different data tools, but of note are the public report builder, and a copy of the Canadian surveys in English and French.
