Canada has pursued conceptual design work and technical studies related to a 20-m segmented mirror telescope (VLOT). This paper provides an overview of the Canadian effort over the last 3 years. VLOT can achieve exciting and significant scientific goals that are not possible with today's 8-meter class telescopes. The scientific promise of instruments on a 20-m telescope enhanced by adaptive optics is particularly exciting. The technical work done thus far indicates that while there are many challenges in designing and constructing a VLOT and its instruments, a 20-m telescope is feasible and achievable without major advances in technology.
