TC Energy Goes All-In on Harvey AI, Signaling Enterprise Legal's Shift to AI-First Workflows

The rollout follows a structured pilot during which TC Energy issued a "Harvey-First" directive — instructing lawyers to route work through the platform before applying their own judgment. That internal mandate produced sustained engagement growth and cleared the path for full deployment across litigation, regulatory matters, corporate transactions, M&A, commercial contracting, and compliance.

The deal arrives as enterprise legal departments accelerate their shift from AI experimentation to operational integration. For years, in-house teams at major corporations tested legal AI tools in narrow, low-stakes workflows. TC Energy's approach breaks from that pattern: a formal directive requiring AI as the default first step signals a meaningful change in how general counsel offices are structuring day-to-day legal operations. Harvey, backed by prominent venture investors and increasingly embedded in large law firms, has been pushing hard into the in-house market — a segment where procurement cycles are longer but contract values and strategic lock-in are often higher.
