A researcher is looking for a list of the 338 federal electoral ridings Revised (2013) grouped by census metropolitan area (CMA).
Answer
Here is a note that explains how the FEDs were formed for the Census and the NHS (this is valid for both the 2011 Census and the 2011 NHS):
The Constitution of Canada requires that the number of seats in the House of Commons be recalculated and the boundaries of federal electoral districts (FEDs) be reviewed after each 10-year census to reflect changes and movements in Canada's population. This process is known as the redistribution of federal electoral districts. A 2013 Representation Order was proclaimed with 338 federal electoral districts, and reported in the Canada Gazette on October 5, 2013.
Many of the 338 federal electoral districts (2013 Representation Order) do not fully align with the 2011 Census geographic structure. To tabulate the data from the 2011 National Household Survey, the 2011 dissemination block structure was used. In some cases, dissemination blocks were split between FEDs and had to be assigned to a single FED for the purpose of tabulating the data. For this reason, and also due to random rounding and weighting, the 2011 National Household Survey data for these FEDs may not match the population counts reported in the Canada Gazette. In addition, the 2011 National Household Survey is based on the population in private households rather than the total population.
