Yeah, they get into something called "deep stall". I don't know the
aerodynamics exactly - something about the wing and the canard being
stalled at the same time or something

They are designed not to. If the CG is too far aft, or the airplane is
constructed wrong, then yes...a deep stall can occur (main wing stalls
before the canard, causing more pitch-up rather than a recovering
pitch-down). But a properly designed, constructed, and loaded canard
airplane will have the canard stall before the main wing, preventing the
deep stall from happening.

In particular, the Velocity being referred to in this thread was most likely
constructed and loaded correctly and did not get into a deep stall. If the
elevator is held nose-up, the canard will stall, recover, stall, recover,
etc. without the main wing stalling at all (preventing an overly dramatic
descent rate).
