Mega Bloks is a popular Canadian brand of construction toys, famous for its oversized blocks for preschoolers (Mega Bloks) and smaller, LEGO-compatible blocks (Mega Construx) for older kids, focusing on imagination and skill-building through play. Founded by the Bertrand family in 1967, it grew to become a major competitor in the construction toy market, eventually becoming a subsidiary of Mattel in 2014, offering products for all ages and popular themes like Pokémon and Halo.
