Estimated areas, yield, production, average farm price and total farm value of principal field crops, in metric and imperial units^{1 2 3 4}

Farm surveys collect data from Quebec, Ontario, Manitoba, Saskatchewan and Alberta at all five survey occasions during the crop year (which extends from the December to the following November occasion). However, data are collected twice a year (in the June Farm survey on seeded areas and in the November Farm survey on final crop production) for Newfoundland and Labrador, Prince Edward Island, Nova Scotia, New Brunswick and British Columbia, which represent between 2% and 4% of national totals. As of July 2014 for the Atlantic provinces and British Columbia, July and September production estimates are calculated using the final estimates of the last three crop years. The harvested area is first estimated based on the ratio obtained from the sum of harvested areas of the last three years over the sum of the seeded areas of the last three years. This average ratio is applied to their 2014 reported seeded acreage from the June survey. This estimated harvested area is then multiplied by the average yield of the last three years to estimate production.

Totals may not equal the sum of their parts due to the use of conversion factors or rounding of fractions to whole numbers.

On December 13, 2016, estimates for category "Wheat, all excluding durum wheat" in 2016 were corrected for the following geographies: Maritime provinces, East and Canada.

Starting in June 2018, the Canadian total for a given crop includes all provincial estimates, whether they are published or not based on quality and confidentiality factors. Note that overall, the estimates of the most important crops non-published in the past generally represent less than 5% of the Canadian total.

Metric data was previously released in CANSIM table 001-0010, which is no longer available as of December 2017. Metric and imperial data are now both included in table 32-10-0359-01 (previously known as 001-0017).

Data for British Columbia begin in 1910.

Estimates are not available for small area, which were grown in Alberta and Ontario between 1943 and 1945. Data begin in 1996 for Quebec, in 1983 for Ontario, in 1955 for Alberta and in 1967 for British Columbia.

Data were discontinued between 1932 and 1966 for Quebec. Data begin in 1941 for Manitoba, in 1979 for Alberta and in 1983 for Nova Scotia.

Data begin in 1952 for Manitoba and in 1960 for Saskatchewan.

Most of the soybean crop is grown in Ontario but it was also grown in small areas in other provinces in the years 1942 to 1945. The total for Canada includes this production, but provincial data are not shown. Data begin in 1991 for Prince Edward Island and in 1986 for Quebec. Data for Manitoba begin in 1956 and were discontinued in 1960.

Data for Saskatchewan begin in 1943 and were discontinued in 1946, and began again in 1963. Data for Alberta begin in 1958 and were discontinued in 1974, and began again in 1986.

Data begin in 1908 for Ontario, in 1976 for Canada, Prairies and Alberta, in 1981 for Saskatchewan, in 1986 for Prince Edward Island, Nova Scotia, New Brunswick, Quebec and Manitoba. Average farm price and total farm value begin in 1978.

Winter wheat remaining and fall rye remaining indicate the areas seeded in the fall of the previous year that are remaining after winterkill.
