CFLdb's raw data is all provided and verified from original sources. The CFL has provided the bulk of historical information that the basis of data in the database was verified against. Current data, including player career stats and game stats, are sourced directly from official CFL feeds. All of the standings, records, etc. are compiled from raw data by CFLdb Statistics. Any errors in compiled data are CFLdb's own. Compiled data can become out of date as corrections are made. Therefore, it is important the readers and users of CFLdb report issues they detect on pages so the problem may be corrected.
Data outside the CFL's concern (not relating to the CFL, CFC, IRFU or WIFU leagues) has been independently sourced and compiled by contributors to CFLdb. This includes CFL exhibition and pre-season contests which the CFL did not provide in their donated data.
Sources for data provided on CFLdb Statistics are attributable to the following as original sources or verifying sources used by contrbutors or CFLdb.
And as a starting point for finding original sources:
Game weather data is provided by Environment Canada. Stadium conditions are provided by the CFL and parsed by CFLdb for consistency and brevity.
Television ratings have been primarily sourced from a number of media reports, specifically:
Where possible, game pages will include a link to the source for TV ratings.
Historical numbers are BBM 15 minute average number of viewers to my understanding as published by the sources unless otherwise noted. The latest (2016 to 2017) numbers are Numeris average minute audience overnight ratings. Broadcast TV ratings are now dead, and no longer available.
Various media reports, CFL.ca and CFL Facts, Figures & Records have also been used as sources of television ratings published herein.
CFLdb would not exist without these sources and we thank them. CFLdb would also like to thank the following people who have handled the task of managing Canadian Football data and stories over the decades.
