To find this answer, you must first follow the instructions in your link.  This gets you to this page.  From there, you can click on the links on the left to each province of Canada.  This shows you figures for each province in turn.  The most recent year for which data is provided is 2011.  You find the inflation rate for that year by looking at the second line of bold-faced numbers, under the heading “% change from previous year.”  Do not simply look at the top line of bold as that is only the CPI and not the change in the CPI (inflation).

By looking at all of the provincial data, we can see that Nova Scotia had the highest rate of inflation in 2011.  Its rate was 3.8%
