Method and sources
End dates come from the Government of Canada's proactive disclosure of contracts over $10,000 (delivery or contract-end date) and from CanadaBuys award notices (contract end date), published under the Open Government Licence – Canada.
An end date is not a re-tender announcement: the buyer may extend, exercise an option, use a standing offer, or stop buying. Treat each row as a lead to verify. Amendment rows that repeat a contract's running total are collapsed, so totals are approximate.
