The Greenbelt isn't the problem. Single family neighbourhoods in Toronto are the problem. The single family house has no place in a city the size of Toronto. It is impossible to accommodate the population that way. This is why the prices are so high for houses - there will never be enough of them. False expectations are created that everyone can live in a detached house. Politicians are too afraid to suggest otherwise. Simply thinking this intensification will all magically happen on major avenues in Toronto is delusional. Toronto needs to make some hard land use decisions in the central part of the city i.e. the residential neighbourhoods - not just main streets -  have got to intensify.
