Why don't we see more canard gliders?

Engineering complexity. Discussed a few years ago on homebuiltairplanes. A few members there actually design and build custom gliders, and experimental/race gliders.

Because there are times when a glider needs to fly at or near its max C/L, which is getting close to the critical AOA. The problem with canards is they are inherently designed to keep the main wing reasonably far from the critical AOA to avoid a stall (or worse, a deep stall), and you can't approach the main wing's max C/L.

Meaning you give up low speed performance or you build a bigger wing.
