I can provide a bit of information to get all the information you might be looking for. I think people from the NAC would be better positioned than me to talk about it. Of course, the NAC often presents performances that tour nationally or internationally, so these won't be presented only here in the national capital region, but also in Toronto, Calgary, Vancouver, and Montreal.
What you see here at the NAC is not exclusive to the NAC. It costs a significant amount of money to create a new dance performance; therefore, you have to present it to a bigger audience than in only one city, and these productions tour.
The NAC also does co-productions with dance companies across the country and it ensures that what is presented here is the best work of Canadian dancers and choreographers from all over the country. That work can be presented on a national basis in different regions of Canada.
