Marcia Mills

Counsel | Co-Leader, National Security Fasken
The laws of tendering and government contracts are complex – understanding them can be the difference between a procurement that ends in contract award and one that ends in a dispute.

Marcia Mills is counsel to Fasken’s Procurement, International Trade & Customs, and Technology, Media and Telecommunications groups. Prior to joining Fasken, Marcia worked in both the public and private sector as external and in-house counsel in defence, aerospace & security and information technology; most recently as counsel to Public Services and Procurement Canada (PSPC), the central purchasing agent for federal departments and agencies. During her 10-year tenure at PSPC, she provided strategic and legal advice for some of Canada’s largest defence and Major Crown procurements.

With more than 20 years of private and public sector experience in procurement, government contracts and security, Marcia draws upon her in-depth understanding of the defence and government sector to provide practical and strategic advice with respect to of evolving national security issues, including supply chain security, security requirements for government contractors, national security exceptions under trade agreements, procurement and other considerations under the Defence Production Act, and import and export controls for defence-related goods and services, and controlled goods.

Public procurement is not “just” a commercial transaction; but rather, occurs within the wider sphere of regulations and policy, international and national trade commitments and the public eye. For private businesses, participating in or running a procurement can be time and labour intensive. Whether her clients are suppliers or buyers, private or public sector, subject or not subject to Canada’s trade agreements, Marcia understands their perspectives and issues, providing relevant and useful legal and strategic advice throughout the entire procurement cycle - from early engagement/requirements definition, to solicitation drafting and bid preparation, bid evaluation, contract award and negotiation, contract management and the bid dispute process.
