Landon Sim, 21, is in rookie camp with the Marlies after signing as a free agent, intent on climbing from junior success to pro status. A summer training moment with John Tavares created a tangible Leafs link, underscoring a lineage of competitiveness and earned grit. Sim’s path weaves through Memorial Cup pedigree, Blues exhibitions, and a network of rising Maple Leafs prospects, with a Montreal weekend tournament as a proving ground.

He’s driven by a family legacy (his father Jon Sim won the Stanley Cup) and the mentorship style of Craig Berube, a coach who values hard work. The feature traces his ties to Easton Cowan, Ben Danford and Jacob Quillan, his London Knights roots, and his bid to translate AHL promise into an NHL opportunity.
