I do not know much about that program, but as far as I know, it is an investigative group made up of police forces from various regions. In your case, it would involve the Montreal, Longueuil and neighbouring police forces. The officers involved were investigating members of street gangs. This is an extremely effective approach, because it brings together the knowledge and expertise of each police force.
I should point out that these individuals know no boundaries. Only police forces set boundaries; street gangs have none. The beauty of these teams is that they are interjurisdictional, they can follow these criminals over a larger territory.
However, I must say that this type of cooperation also exists more informally among police forces. In cases of human trafficking, for example, we have no other choice, because it is all over Canada. I can tell you that we have excellent relationships with all other police forces when it comes to these investigations.
