Explanatory notes – all grains

1. The majority of the statistics presented in this publication are collected under the authority of the Canada Grain Act. Primary and process elevator companies report their grain handling activity on a weekly basis while terminal and transfer elevator information is received daily. Terminal and transfer elevator figures are current to the day but a lag exists in primary elevator statistics due to the large numbers of reporting points and the processing required at head office. As most deliveries occur at the primary level and most disposition occurs at the terminal level, an imbalance occurs in reported weekly statistics.
2. Statistics represent stocks and handlings of grain net of dockage at licensed Canadian elevators only. Although still termed 'net', terminal elevator shipments and exports of flaxseed and canola include approximately 2% dockage.
3. Domestic disappearance refers to grain:
   1. processed in a licensed elevator,
   2. shipped from a licensed to an unlicensed process elevator, or
   3. shipped from a licensed elevator for use as food, feed or seed.
   
   Canadian grain processed in Canada is included in domestic disappearance whether or not the end product is consumed domestically or exported.
4. In addition, Statistics Canada indicates exports to the United States: 538 800 (360 100) tonnes of Wheat excluding Durum, 116 300 (133 300) tonnes of Oats, 20 900 (37 400) tonnes of Flaxseed, 39 000 (33 100) tonnes of Canola, and 142 200 (93 600) tonnes of Corn between August, 2008 and February, 2009. Year ago figures are shown in brackets.
5. Stock adjustments due to elevator weighovers, drying, grain cleaned ex dockage and handling adjustments due to reporting revisions are incorporated weekly into cumulative statistics. Other stock adjustments occasionally result from reporting lags and yearly reporting revisions are included only at year end.
