The Hole Story

The Student Design Competition is held every year. The program challenges Ontario university and college students to put their design skills to work on an Ontario aggregate extraction site to create a rehabilitation design that maximizes the opportunities that the site will offer. Winners are awarded monetary prizes and winning entries are displayed at OSSGA's Annual Conference. 

Students in any post secondary program involving landscape architecture, planning, ecology, environmental design, engineering, hydrology and georgraphy, just to name a few, are encouraged to enter.

Submission Deadline:

  • May 5, 2017 (for classes participating during the winter semester)
  • January 5, 2018 (for those participating during the fall semester)

Projects are judged annually in January following shortly after the submission deadline.
