I cannot answer for the restaurant industry. However, I can say that, as dietitians, we are quite concerned by the fact that Canadians are not consuming enough dairy. A great deal of research is being done to understand how we can help them change their behaviour. We do not find the price of dairy to be an obstacle for most Canadians. In fact, the greatest obstacle is the fact that they do not realize they do not consume enough dairy products. The second greatest obstacle is the fact that they are not all that concerned with the problem. A poll conducted by Ipsos and Dietitians of Canada showed that cost was only an obstacle for 6% of the Canadians surveyed.
