What is GNCTR?


  • Held every winter since 1974, the Great Northern Concrete Toboggan Race – otherwise known as GNCTR – is an annual engineering competition.
  • Over 20 engineering schools across Canada compete every year, each with teams of 10-30 student members.
  • The nation-wide event gives engineering students the opportunity to work collaboratively and apply technical knowledge attained in classes towards an exciting student-run competition.
  • There are many different areas for student involvement, whether it be designing and fabricating the steel frame, producing different concrete mixes, designing and constructing the technical-exhibition or assisting with the technical report.
  • As this competition is extra-curricular, it also requires good time management to balance university deadlines with competition deadlines.
  • The toboggans are raced down a snow hill at a host University on the final day of competition.
