How to find and win government tenders in Ottawa (2026)
Where the City of Ottawa posts construction tenders — MERX for larger work, the City Quotations Portal for smaller — plus the federal layer, and what it takes to win as an Ottawa contractor.
By Joseph Morrison · Founder, Cornerstone Contracts
Ottawa is two procurement markets in one city. There's the City of Ottawa's own municipal program — roads, water, transit, parks, and facilities — and there's the federal government, which concentrates a huge volume of building and fit-up work in the capital. They post in different places, and missing either one leaves money on the table.
Here's where Ottawa public construction work shows up and how to win it.
Where Ottawa posts its tenders
The City of Ottawa splits its postings by value:
- $125,000 and over is advertised on MERX, the City's electronic bidding service.
- Smaller work (generally under $100,000) runs through the City of Ottawa Quotations Portal, with some opportunities also posted on Ottawa.ca or sent to selected suppliers based on past similar procurements.
Then there's the federal layer, which in Ottawa is large:
- Federal work — buildings, facilities, and fit-ups across the National Capital Region — posts on CanadaBuys.
Watching MERX, the City Quotations Portal, and CanadaBuys together is what full Ottawa coverage actually looks like.
Who's buying
On the municipal side, the City's departments — infrastructure and water services, public works, parks and facilities, and transit — carry the volume. On the federal side, Public Services and Procurement Canada and individual departments tender a steady stream of building work in the capital. Ontario ministries and the broader public sector add a third layer.
How to register and bid
- Register on MERX to see and bid the City's larger work. Viewing is generally free; submitting a bid carries a fee, and registration requires a credit card on file.
- Watch the City of Ottawa Quotations Portal for the smaller opportunities — useful, lower-competition work that's easy to miss.
- For the federal stream, our CanadaBuys guide for contractors walks through registration and finding fits.
What it takes to win
- Bonding and insurance scale with project size; larger City and federal work often requires performance and labour-and-material payment bonds.
- Prequalification appears on bigger capital projects — get on the lists early.
- A complete, compliant submission is what separates winnable bids from lost ones. See our guide to winning Canadian construction tenders.
