Canadian Buick Car Serial Numbers 1935-1964

In cases where U.S.-built cars were imported into Canada, they used the U.S.-style numbering formats shown above. Canadian built cars used the following serial number format, which was common to all General Motors of Canada divisions for 1935-1966 with only minor changes over the years. For 1935-1957, the car and engine serial numbers are stamped on a plate under the hood. For 1958-1964, the car serial number is stamped on a plate attached to the driver’s side door post. For 1935-1942 cars were built or assembled at Oshawa, ON and Regina, SK and engines were built at Walkerville, ON. For calendar years 1951-971, cars and engines were built at Oshawa, ON only. For 1951-1964, only the Custom and Custom Deluxe (same as U.S. Special and Special Deluxe models on exterior, but with some Oldsmobile trim on the interior), Special, Special Deluxe, Skylark, LeSabre, Century, Invicta, and Wildcat models (cars and engines) were built in Canada. The car serial number consists of nine to eleven digits depending on the year. Information on decoding Canadian Buick car serial numbers and paint codes is available from the “Catalog of Canadian Car I.D. Numbers” by Bill Watson (ref. 10) and from the Canadian Maintenance Manuals (ref. 2). Note that all references contain errors and omissions. table 2.2 shows the starting car and engine serial numbers for 1951-1966 for the U.S. and Canada. 1935-1964 Canadian built cars used the following serial number format:

1st digit is the last digit of the model year:
  1 = 1941, 1951 or 1961 5 = 1935, 1955 or 1965 8 = 1938 or 1958
  2 = 1942, 1952 or 1962 6 = 1936, 1956, or 1966 9 = 1939 or 1959
  3 = 1953 or 1963 7 = 1937 or 1957 0 = 1940 or 1960
  4 = 1954 or 1964    

2nd digit is the car make: 4 = Buick

3rd digit is the car series:
  0 = Special (1964)
  1 = Special Deluxe (1964)
  2 = Special (1941)
  3 = Custom (same as U.S. built Special, 1951-1953), or Skylark (1964)
  4 = Series 40 (1935), Special (1936-1942, 1954-1958) or LeSabre (1959-1964)
  5 = Series 50 (1935), Super (1940-1942)
  6 = Series 60 (1935), Century (1936-1942, 1954-1958), Invicta (1959-1962), Wildcat (1963-1964)
  7 = Roadmaster (1940-1941)
  8 = Roadmaster (1936-1939)
  9 = Series 90 (1935), Limited (1936-1940)
4th and 5th digits are the model number:
  See table 2.3 for the Canadian model number list (based on digits 2-5) and their U.S. equivalents for 1951-1966. Canadian and U.S. model numbers are the same starting in 1959, except in cases where no corresponding U.S. model exists. Bill Watson’s book states the use of the letter D for 1951-1955 in the car serial number for G.M. of Canada deluxe models, but the examples below show that this is not the case for Buick. Thus, for 1951-1953 Buick’s it is not possible to distinguish between standard and deluxe models based upon the car serial number alone. In 1954 Buick had separate model numbers for deluxe models and Buick did not use the deluxe designation in 1955.
6th digit is the number of cylinders (1955-1957 only):
  if year = 1955-1957 then 6th digit = 8 = V8 (all Buicks were V8’s during these years)
Last four to six digits are the sequential production number unique to that particular car:
  four digits for 1935-1938, starting at 0001 for Oshawa ON, 8001 for Regina SK (except for 1937-1938 Oshawa ON built cars where starting number varies by car model)
  five digits for 1939-1942, starting at 00001 for Oshawa ON, 80001 for Regina SK
  five digits for 1951-1963, starting at 00001 for Oshawa ON
  six digits for 1964, starting at 000001 for Oshawa ON built Special/Skylark
  six digits for 1964, starting at 050001 for Oshawa ON built fullsize cars
Note: for 1935-1942 the leading zero of the sequential part of the serial number is omitted on some cars. table 2.2 Starting U.S. and Canadian Built Car and Engine Serial Numbers 1935-1966
