How to bid on web design contracts in Ontario

16 web design tenders open in Ontario right now, from 11 public buyers.

1. Where Ontario posts web design tenders

Ontario public buyers post web design solicitations on Ontario's OTP and BidsAndTenders and increasingly on national platforms like CanadaBuys. Municipal buyers in Ontario may also use Biddingo or BidsAndTenders. Checking each portal daily is how opportunities get missed — a single aggregated feed solves it.

2. What documents you need

Most Ontario web design solicitations require: proof of insurance (typically $2M+ liability), WSIB or provincial workers' compensation clearance, relevant trade certifications and licenses, and references from comparable public work. Federal buyers add security clearance requirements. Read the full RFP — requirements buried on page 40 disqualify more bidders than pricing does.

3. Never miss a deadline

The next web design deadline in Ontario closes 2026-10-01. Deadlines cluster at month-end and quarter-end. A weekly digest with your trade and province pre-filtered catches everything without daily portal-checking.

4. How web design contracts are valued

Public buyers in Ontario follow procurement thresholds: smaller purchases may use simplified quotes, while larger web design projects require formal RFPs with published evaluation criteria. Winning bids typically price 5–15% below the engineers' estimate on construction-adjacent work.
