I would like to return to Canada too in view of the worsening political situation. In a year or latest in 2 years, I will move back with my 2 kids. When they grow up, I think HK will no longer be a good place for work (reduced foreign investment because of unstable political environment and poor english standard of HK workforce) and for living (air pollution).
I think education is not the main concern for prospective emigrants as one can always opt for international schools in HK.
