士嘉堡輕鐵
In 2007, mayor David Miller included the refurbishment of the Scarborough RT using modern light rail transit as part of his Transit City plan. The light rail line would have run between Kennedy station and Sheppard Avenue East via Scarborough Town Centre. The line would have used the right-of-way of the Scarborough RT, which would have been shut down for conversion to light rail, requiring bus substitution. Construction would have lasted 3½–5 years and cost about $2billion plus an unknown cost to redesign the connection at Kennedy station.
