Abstract
As a result of affiliation between the Hudson's Bay Company and the Royal Society a relatively large number of instrumental temperature records are available from York Factory and Churchill Factory on the southwest of Hudson Bay beginning in 1768. The nature of these records, details of the instruments and information about the observers are presented. The major difficulty with the records is that the number of observations and the time of observation varied considerably. Adjustment factors were calculated for all of the combinations using a modern record maintained at the Churchill airport. By combining the Hudson's Bay Company record with data recorded by members of the Royal Canadian Mounted Police after 1852, and up to 1910, a long and relatively continuous record of daily and monthly average temperatures has been created for Central Canada.
