The professor does not owe a thank you letter to someone who sent their unsolicited opinion. If you ever attend a municipal council meeting, you would know he is right. The builders know they market and know that customers want single-family homes. The councils know they take their marching orders from the province and must follow the "places to grow" legislation, that dictates new housing must be intensive, near transit lines, etc. etc. Which people, apparently, do not actually want to live in, based on what we are seeing now. As they say, communism looks good on paper....
