What are the exact specifications needed for a glider to be considered a Canard Configuration?

There are two horizontal aerodynamic surfaces in elastic launch gliders. The larger surface is the primary source of lift and is considered the "wing." The smaller is a stabilization source and is considered the "horizontal stabilizer." Canard configurations place the horizontal stabilizer in front of the wing (reverse that of traditional layouts.) No aerodynamic surfaces may be behind the main wing.
