"Presentation of the brand – Live Lanaudière The symbol is inspired by the L
of Lanaudière. The cross-curved pattern illustrates the six MRCs that make up
the region. It also refers to the different characteristics of its territory, in
motion: the river, the mountains, the country roads, the highways." Dave Fowler, 13 February 2022
