Yes, indeed, Monsieur Ménard, they can lay charges and link those charges to the existence of a criminal organization. The charge is not laid under section 467.1. That's simply a definitions section. The charge will be laid under section 467.11, participating in an activity; section 467.12, committing an offence for the benefit of; or section 467.13, instructing somebody to commit an offence.
In the circumstance you're describing, the applicable offence would presumably be section 467.12, committing an offence in association with, for the benefit of, or at the direction of a criminal organization. They could certainly lay that charge in addition to the drive-by shooting if they could show that the drive-by shooting was linked to a criminal organization.
