This is the last years the Ndrangheta seek more and more to establish in the United States is the most lucrative markets for a criminal organization like them for drugs. We have been able to see if it is the last years with collaborations with the families of New-York notably with the father and the son Gigliotti who collaborated with the Genovese.
For the Camorra some sources say they would have 200 members in the US but I doubt I do not think they are powerful enough to settle in the United States or even in Canada knowing that they already have 2 main Italian criminal organization Cosa Nostra and Ndrangheta.
For the Sacra Unita Corona I do not have too much information about them they would be present in small numbers in the usa. No known presence in Canada I did not have if they are powerful enough to be a force in this country the same if on their territories in Apulia they freed Sicilians and Calabrian as well as Albanians to have same for the Stidda.
