The Maple Leafs announced their annual Dev Camp today.

Apologies for the terrible quality, for the original PDF, you can go here:

Players will undergo medicals and on-ice testing on Sunday, July 2, while the first full-team on-ice session and media availability will take place on Monday, July 3, at the Ford Performance Centre.
