From the very early concept presented in 2001 at the Venice conference ’Beyond Conventional AO’, to the first on-sky MOAO prototype systems, exactly 10 years have elapsed. End of 2010, the pathfinder instrument called Canary obtained the first open-loop, tomographically compensated images on the WHT. What were the challenges, and what was demonstrated ? How long will it take for real astronomical MOAO system to be installed on an ELT, and what will be the future steps ? We present the Canary program, and discuss how these achievement contribute to build the future MOAO systems of the ELT.
