For years, the standard career advice given to ambitious women has been simple: Find a mentor.

Organizations have poured resources into matching female talent with seasoned professionals to provide guidance, feedback, and a sounding board. Mentorship is undeniably valuable for personal development. But when it comes to actually breaking through the “broken rungs” of the corporate ladder, the data tells a different story.

Women are over-mentored and under-sponsored.

To understand the persistent structural barriers holding women back, The A Effect recently convened a roundtable in Toronto with top women executives. Among the many insights shared, which will be featured in our upcoming white paper, one theme stood out immediately: the critical difference between mentorship and sponsorship.

The Evaluation Bias: Potential vs. Proven Experience

Before understanding why sponsorship is so vital, we have to look at how advancement decisions are actually made.

At the executive roundtable, Akanksha Malik, VP, Claims at Intact, highlighted a subtle but pervasive bias in how talent is evaluated for cross-functional mobility or senior roles.

“For men, it’s almost assumed they can move across functions, they’re seen as versatile,” Malik observed. “For women, we question: do they have the financial acumen? The leadership posture? The resilience? Those questions don’t get asked in the same way.”

When men are promoted based on assumed potential and women are scrutinized for proven experience, a mentor’s advice is no longer enough to bridge the gap. A woman doesn’t just need someone to tell her how to navigate the system; she needs someone with the power to change the rules of the room.

She needs a sponsor.

The Defining Difference

While a mentor gives you perspective, a sponsor gives you opportunity. Mentors talk to you. Sponsors talk about you, specifically when you are not in the room.

Malik captured this distinction perfectly during the roundtable:

“The sponsor has to put their neck on the line for you. When they’re in the room and under pressure, are they willing to say, ‘Yes, I stand behind this person’? That’s what makes the difference.”

Sponsorship is transactional and high-stakes. It involves a senior leader actively spending their own political and social capital to advocate for a protégé’s promotion, secure their placement on high-visibility projects, and protect them from unfair scrutiny.

What the Data Says About Sponsorship

The impact of this advocacy is highly measurable. External research consistently shows that sponsorship is the ultimate accelerator for diverse talent:

• The Promotion Gap: According to research from Coqual (formerly the Center for Talent Innovation), professionals with sponsors are 22% more likely to be satisfied with their career advancement rate than those without. 
• The Pay Bump: A study by Payscale revealed that having a sponsor translates to a quantifiable financial advantage, often resulting in an 11.6% larger pay increase compared to those who merely have a mentor.
• The Gender Divide: Despite these benefits, Harvard Business Review reports that women are significantly less likely than their male peers to be actively sponsored by senior executives, often leaving them “stuck” at the director or mid-management level.

Shifting from Advice to Advocacy

If organizations are serious about closing the gender gap at the executive level, they must move beyond simply assigning mentors. Leaders must be trained, encouraged, and held accountable for actively sponsoring diverse talent.

Talent has never been the issue. 80% of women consider themselves ambitious. The question for organizations in 2026 is no longer how to develop women, but whether their current leaders are willing to put their necks on the line to pull them up.

This topic is just one piece of a much larger conversation happening across Canada’s corporate landscape. In late August 2026, The A Effect will release our comprehensive white paper, The Progression Advantage, detailing the systemic changes organizations must make to build a true gender parity ecosystem.
