This page is generated from SIGNAL's own database each time it is requested (cached for up to 30 minutes). The last morning scan finished September 27, 2026. Counts include every open posting whose closing date has not passed, from sources SIGNAL reads with its published SignalBot identity. Trade counts come from SIGNAL's classifier, so one posting can count toward more than one trade. Public buyers across Canada must open contracts above set values to competition under the Canadian Free Trade Agreement, which is why these postings are public; federal ones come from CanadaBuys, the Government of Canada's tender service.
