I looked into this. There were a handful of interactions with the Prime Minister's Office and the WE organization around the Canada summer student grant between then and the launch of the program. There was only one prior to the launch of the program. It was in early May, when one of the policy staff did what is very normal in their jobs, which is to speak to stakeholder organizations.
It was a very general discussion. They actually redirected the stakeholder, the WE organization, to ESDC officials. ESDC was a more appropriate place to get answers for the questions they were asking.
