Some other distant counties like Matawinie and Les Laurentides have high enough interchange numbers to join the Montreal CSA but lack urban areas large enough to form micropolitan areas. Also, the US Census Bureau says that in addition to having an urban area of at least 10,000 people, micro/metro areas need to have sufficiently strong ties to the rest of their area. Joliette, Sorel and Saint-Hyacinthe are very much the main hub of their counties, so what ever these requirements may be, I'm sure they will qualify. I'm a bit less sure with Lachute though since other parts of Argenteuil have significant ties with Hawkesbury, Montreal and other parts of the Laurentides region. Still, Lachute holds the vast majority of Argenteuil's jobs, so I suspect it would qualify for forming a micropolitan area.
