How to find and win government tenders in Toronto (2026)
Where the City of Toronto posts construction tenders, how the Toronto Bids Portal and SAP Ariba registration work, and what it takes to win — a practical guide for Toronto-area contractors.
By Joseph Morrison · Founder, Cornerstone Contracts
Toronto is the largest municipal procurement market in the country, and the surrounding public sector — school boards, agencies, the province, and federal sites — adds an enormous second layer. The work is there. The friction is that it's spread across the City's own portal plus several aggregators, each with its own login and alerts.
Here's where Toronto public construction work gets posted and how to be ready to win it.
Where Toronto posts its tenders
The City of Toronto advertises Notices of Intended Procurement on its website through the Toronto Bids Portal (TO Bids). Selecting a posting takes you to the SAP Business Network (Ariba), where you view the documents and submit your bid — and you must complete SAP Ariba registration to view or bid on City solicitations.
Around the City, the rest of the GTA's public work shows up across several places:
- Broader public sector — school boards, agencies, hospitals, and provincial bodies — posts on MERX, bids&tenders, and Biddingo, depending on the buyer.
- Federal work in Toronto posts on CanadaBuys.
No single portal is complete, which is the recurring tax on public bidding in a market this size.
Who's buying
The City's divisions — transportation services, Toronto Water, parks and facilities, and major capital programs — carry the municipal volume, alongside agencies and corporations. Add Ontario ministries, the health and education sectors, and you have one of the densest concentrations of public construction work in Canada.
How to register and bid
- Register on the SAP Business Network — a standard account is free.
- Check first whether your company already has an account (or email supplychain@toronto.ca) so you don't create a duplicate, which causes problems at submission.
- Complete your business profile, then watch TO Bids for new Notices of Intended Procurement.
For the aggregators that carry the surrounding public sector, our guides cover finding federal work on CanadaBuys and using MERX for Canadian construction.
What it takes to win
Finding the tender is step one; winning it is about a disciplined, compliant bid:
- Bonding and insurance (bid, performance, and labour-and-material payment bonds; CGL) scale with project size.
- Prequalification is common on larger Toronto capital work — get on the relevant lists before the project you want is tendered.
- A complete, responsive submission wins over a rushed one. Most lost bids are lost on compliance, not price.
