I apologize for not responding in French, although I did understand you as you spoke in French.
That horrible phenomenon of police picking up people, especially people of colour and indigenous people, and driving them out of the city in the wintertime, only to leave them there, really peaked in the 1990s. Four young indigenous men actually died, froze to death, just outside of Saskatoon in the 1990s.
Certainly when I started this work, we would hear this regularly and routinely from some of the young people we worked with. It has not occurred, that we know of, in Winnipeg in recent years.
