Discrepancies between WBWorld Bank and OECD GDP data

I just noticed that basic data such as historical GDPGross Domestic Product (GDP) at market prices in local currency differs between WBthe World Bank (WB) and the OECD. For instance, for Canada between 2010 and 2013:

The differences are not huge, but for data that has presumably been sourced straight from national statistical institutions with no {FX/inflation}inflation correction, I'm still surprised. Also, the WB site mentions for its sources: "World Bank national accounts data, and OECD National Accounts data files."

Edit: Just for fun, I have downloaded the data for France from the "official" sources (INSEEINSEE, and EurostatEurostat which gets its data from INSEE) and here is the result:

For GDP at current (market) prices:

         2010        2011        2012        2013
INSEE    1,998.5     2,059.3     2,086.9     2,116.6 
Eurostat 1,998.5     2,059.3     2,086.9     2,116.6 
OECD     1,997.1     2,058.1     2,086.4     2,117.9 
WB       1,998.5     2,059.3     2,091.1     2,113.7

And for real GDP growth:

         2010    2011    2012    2013
INSEE    2.0     2.1     0.2     0.7 
Eurostat 2.0     2.1     0.2     0.7 
OECD     1.88    2.09    0.21    0.75 
WB       1.97    2.08    0.33    0.29

That's quite depressing ...

Discrepancies between WB and OECD GDP data

I just noticed that basic data such as historical GDP at market prices in local currency differs between WB and OECD. For instance, for Canada between 2010 and 2013:

WB   : 1,662,757,000,000  1,760,011,000,000  1,819,967,000,000  1,881,200,000,000
OECD : 1.66276E+12        1.77001E+12        1.83123E+12        1.89376E+12

Or France:

WB   :          1,998,481,000,000   2,059,284,000,000   2,091,059,000,000   2,113,687,000,000
OECD :          1.99711E+12         2.05812E+12         2.08639E+12         2.11789E+12
[OECD]/[WB]-1 : N/A                 -0.06%              -0.22%              +0.20%

Sources: WB and OECD.

The differences are not huge, but for data that has presumably been sourced straight from national statistical institutions with no {FX/inflation} correction, I'm still surprised. Also, the WB site mentions for its sources: "World Bank national accounts data, and OECD National Accounts data files."

Figures for GDP growth (real) in France in 2013 then differ by 46bp (OECD: 0.74%, WB: 0.29%) (42bp are explained by the difference in current GDP figures, the other 4bp come from differences in GDP deflator data), which is rather material.

Is anyone familiar enough with these 2 institutions' data collection methodologies to explain where these differences come from?
