I have a list in my submission. There are many cities in Ontario. It's also agency specific. Metrolinx used to be a closed shop. Now it appears to be opening up. TTC, of course, is still a closed shop. There are many, not just municipalities or levels of government, but also agencies. Canada Post tries every once in a while to put in a closed-tendering clause in some of the construction they have. PSAC does the same thing. It's an ever-moving target. It's a very political decision.
On April 30th, 2013. See this statement in context.
