BASECAMP Expedition Team Welcomes MH3
Every great expedition needs a voice of experience, a conscience of the culture, and a compass to navigate the uncharted. That's why we're thrilled to announce that Mark Harrison, founder of the MH3 Collective, will be joining the BASECAMP Expedition Team.
BASECAMP isn't just a leadership retreat—it's a mindset. A place where purpose-driven professionals come to sharpen their instincts, challenge assumptions, and reconnect with what matters most. And Mark? He's been doing that for decades.
From building industry-changing ventures to championing education equity, Mark's career has been about forging paths that didn't exist and guiding others to do the same. Through his MH3 Collective—a constellation of ventures including Humanity, Sidekick, T1, and SponsorshipX—he helps changemakers, brands, and communities move from intention to impact.
His journey has been shaped by three role models whose wisdom continues to guide him today:
"It's not what you know; it's who knows you." Accountability and reliability are your real resume.
"Don't be afraid of the truth." In business and life, charity, and academia, you are measured every day.
"Share bad news early." Problems are easier to fix when you're not hiding from them.
And if you've ever heard Mark speak, you know he's got a knack for taking simple truths and turning them into life lessons:
"Get on a plane with a difficult colleague or client. You'll learn more about what makes them tick at 30,000 feet than in 30 emails."
"Your job is to help your client do their job better. That's it. That's the job."
Mark's contributions to our industry, community, and country are profound. He's the co-founder of the Black Talent Initiative and Park Street Education, a CBC business columnist, the Board Chair of Big Brothers Big Sisters of Toronto, and a board member of both CAMH Foundation and the JUNOS.
His accolades include the Harry Jerome Award, the ACA Gold Medal Award, and, most recently, an induction into the AMA Toronto Marketing Hall of Legends.
At BASECAMP, Mark will help guide transformative leadership experiences, challenge the expedition crew with harsh truths, and push conversations toward bold possibilities. He's not just joining the journey—he's here to elevate it.
More BASECAMP Expedition Team members will be announced soon.
For now, let's just say this: the mountain just got a lot more interesting.
