Dozens of students are working hard building some elaborate sculptures built entirely out of canned food in the Annual Canstruction Calgary Competition.

This year’s competition, which involves 14 teams, takes place at South Centre Mall.

Each team has eight hours to complete their sculptures which are built out of canned food which will all be donated to the Food Bank as part of CTV’s Friends Helping Friends campaign.

Students from Langevin School say they have been involved in the competition for the past five years.

Shaelene Standing, a student, says it is a good cause to help out. “It’d be really good for us and me to be creative and just to help out and be a leader in my school and just to help raise awareness for all this.”

The Food Bank says that March is one of the slowest times of the year for donations and many families in the city need help.

The final structures won’t be revealed until Friday.
