One side is going to come with pitchforks, increase racial tension, or vote in an extreme populist while the other is just not gonna come around. Also I am Canadian, it has been stated it is a human right here.
Negative assertion doesn't imply tacit vs. explicitly stated, it implies whether the government is obligated to provide you with it to ensure your right is served.
In America, for example, the right to legal counsel is positively asserted. "If you do not have a lawyer, we will provide one for you." Most other rights, including those explicitly enumerated in the constitution, are negatively asserted. We have the right to keep and bear arms, but it is encumbent on no one to aid me in that right, only the government may not interfere.
What does Canada (or your province) do to ensure that all housing prices are kept to affordability?
