MERX

MERX is Canada’s largest electronic tendering platform: buyers publish tenders, amendments and award notices on it, and bidders register, pay for document access, and submit through it.

How it works for bidders

Create a supplier account, find the opportunity (often cross-posted to the buyer's own site), pay the document fee, download the bid documents, and monitor the platform for addenda — amendments issued near the close usually appear on MERX first, and missing one is a common cause of non-compliant bids.

Who uses it

Departments and agencies at the federal level, most provinces, and large municipalities and universities publish through MERX, alongside their own procurement pages. Québec runs its own system — SEAO — so Québec opportunities often appear there instead.

Common questions

Does MERX cost money?

Yes — there is a fee per bid document (often tens to hundreds of dollars) and optional subscription tiers for search and notification. Fees paid for documents are generally not recoverable if you don't bid.

Is MERX the only place tenders appear?

No. Many buyers also post directly on their own sites, and general aggregators (including pubsec.pro's live opportunity feed) consolidate what's published. Smaller municipalities frequently use their own websites only.

MERX vs SEAO?

MERX is the dominant pan-Canadian platform; SEAO is Québec's mandatory publication system for public bodies subject to Québec contracting rules.
