Open Tenders in Ottawa — 123 Live Today
Data updated August 29, 2026
Ottawa's tender stream has two distinct layers: the City of Ottawa's municipal program — roads, transit, parks, facilities — posted to MERX, and the federal layer, where PSPC, DND, and departments headquartered in the capital tender work that is performed in and around the National Capital Region via CanadaBuys.
The University of Ottawa and the health institutions add steady institutional demand. TenderScan folds the municipal, institutional, and locally-delivered federal streams into the single list below.
