Who are the top federal government suppliers in Canada?

What a supplier ranking can and cannot tell you

The largest suppliers are mostly firms that build and maintain major assets or run national service contracts, so a handful of multi-year agreements carries much of the value. Below them sits a long list of mid-sized firms whose federal work is spread over many smaller contracts, which is where most companies new to federal contracting will compete.

Sellers can use the table to see which departments the leaders work with and where a teaming or subcontracting conversation might start. Public servants can use it to see which firms already deliver at scale for peer departments, and how broad the supplier base is beyond the top of the list.

Each supplier name links to its Publicus page where one exists. See also federal departments ranked by contract value and every supplier with a page.
