Legal Deposit

Legal Deposit is the means by which a comprehensive national collection is assembled as a record of the nation's published heritage and development. By depositing publications with Library and Archives Canada (LAC), publishers ensure the preservation of their works for present and future generations.

According to the Library and Archives of Canada Act and the Legal Deposit of Publications Regulations, Canadian publishers are obliged to send copies of their publications to LAC within one week of the date they are published. The number of copies required is based on the number produced. A description of each publication is entered into the LAC database and is accessible in Canada and throughout the world.

Legal Deposit applies to all types of publications, including books, serials, sound and video recordings, multimedia products, microforms and, since January 2007, maps and online publications. It affects all publishers: individuals, associations, federal government departments or agencies, and those who produce trade or periodical publications.
