On June 24, 2025, I was deeply honored to receive an Honorary Doctorate from the National and Kapodistrian University of Athens, in recognition of my contributions to orthopaedic research, international leadership in the field, and lifelong commitment to medical education

Rather concerning that liberal politician @markhollandlib doesn’t understand his own tax policy. There is NO $250k exemption for incorporated doctors! Increased capital gains applies on every dollar invested through a corporation.

[John Antoniou MD, PhD, FRCSC, FAAOS, FiOR @JohnAntoniou3]

@SteveSaretsky @markhollandlib Sad that he doesn't know where the 250K exemption applies and that it doesn't apply to medical corps. These are very ill informed talking heads that have no clue what they're talking about.

@Val_Plante 20/20/20, thick red tape and bureaucracy, extremely restrictive "master plan" = housing crisis

[Valérie Plante @Val_Plante]

Avant de traiter qui que ce soit d'incompétent, M. Poilièvre devrait comprendre qu’au Québec, le financement fédéral en habitation ne passe PAS par les villes.

Le « gros bon sens », c'est aussi de comprendre les mécanismes de financement propres à chaque province.
