Thank you, Mr. Carney.
I have one question that is more a personal interest of mine. On page 15, you have a chart on CPI, showing “Total CPI” versus “Core CPI”. I've probably asked you this question each time. A number of our programs, particularly for seniors, such as OAS and so on, are attached to CPI, so their increases or non-increases change based on that number.
I've advocated that maybe there should be a seniors' CPI, one that weights things differently and would deal with issues of a higher value to seniors. Driving to and from work doesn't happen that often for many seniors, so the cost of fuel, as in gasoline, shouldn't play as big a role. The core inflation, the blue line on the chart, is a lot flatter; it doesn't change nearly as much as the variances in the total CPI.
Can you explain to me briefly what the difference is between the two in terms of weighting and what plays a bigger and lesser role?
