Welcome to Cornerstone Contracts

Welcome to the Cornerstone Contracts blog.

We built Cornerstone to fix one of the most painful parts of Canadian construction: finding the right public tenders and getting a strong proposal out the door before the deadline. Estimators and project managers lose hours every week watching procurement portals, hunting for addenda, and formatting bid documents from scratch — time that should go into the work itself.

Cornerstone scans the Canadian procurement boards every day, scores each posting against your trade, region, and project size, and drafts a compliance-aware proposal for any tender you choose to pursue. The scoring is deterministic and explainable — here's how it works — and AI is reserved for drafting, never for deciding what fits you (why that matters).

What you'll find here

This blog is the practical reference we wish every contractor had:

• Finding tenders — where public work is posted in each province, board by board.
• Bidding and winning — the tender types, prequalification, COR, bonding, insurance, prompt payment, and the proposal habits that win.
• Province guides — complete walkthroughs for Alberta, Saskatchewan, and British Columbia.

Everything here is written to be useful whether or not you ever sign up — the content earns its place by being accurate, not by being a sales pitch. That is one of our principles.
