  "thesis": "A cut to development charges can make a substantial difference to a housing proposal. In parts of downtown Oshawa, however, the city's charge is already zero. Meanwhile, northern growth areas still need physical infrastructure, and one Kedron developer is proposing a striking change in housing mix. Together, these details suggest that the next supply response will depend on where a project sits, what it pays today and what kind of home it plans to build.",
