DTCC Data Repository (U.S.) LLC (DDR) supports derivatives trade reporting under Canadian regulations for all Canadian provinces and territories (Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario, Quebec, Saskatchewan, Nunavut, Northwest Territories, Prince Edward Island, Yukon, Newfoundland and Labrador).
DDR accepts trade submissions directly from reporting firms as well as through third-party service providers.
Reporting is single sided with the derivative dealer most often reporting the trade. In other instances, the counterparties agree as to which counterparty reports the transaction.
Additional information on the model rules can be found on Canadian Securities Administrators website - https://www.securities-administrators.ca/
