Léon Mugesera (born 1952) is a convicted genocidaire from Rwanda who took residence in Quebec, Canada. He was deported from Canada for an inflammatory anti-Tutsi speech which his critics allege was a precursor to the 1994 Rwandan genocide and in 2016 sentenced to life in prison 
Time in Rwanda
In a speech given on November 22, 1992 in Rwanda, Mugesera allegedly told 1000 party members that "we the people are obliged to take responsibility ourselves and wipe out this scum" and that they should kill Tutsis and "dump their bodies into the rivers of Rwanda."  This statement does not exist in the official translation of the speech, as presented in a legal document before the Minister of Citizenship and Immigration of Canada on August 8, 2003.
Do not be afraid, know that anyone whose neck you do not cut is the one who will cut your neck.— Léon Mugesera on 22 November 1992, http://www.law.utoronto.ca/documents/Mackin/mugesera.pdf
Following this speech, the Rwandan Minister of Justice, Stanislas Mbonampeka, issued an arrest warrant against him for inciting hatred. He fled with his family first to the Rwandan army and then to Quebec City in Quebec, Canada. Shortly afterwards, Mbonampeka resigned as Minister of Justice in protest.
Accusation of war-crimes
Philip Gourevitch, author of We Wish to Inform You That Tomorrow We Will Be Killed With Our Families, claims that Mugesera's 1992 speech gave necessary momentum to the anti-Tutsi hysteria that led to the genocide, saying that "[Mugesera] was one of the first to go in a major public speech and say, 'Look, our mistake in the past with the Tutsi minority has been allowing them to survive, has been allowing them to live. We must get rid of them.'" This statement does not exist in the official translation of the speech, as presented in a legal document before the Minister of Citizenship and Immigration of Canada on August 8, 2003.
In 1995, Canadian government lawyers began deportation hearings against Mugesera. Two immigration tribunals ordered his deportation, however, the Canadian Federal Court of Appeal overturned these verdicts. Justice Robert Décary, writing for the Court, held that there was no evidence linking the 1992 speech with the genocide which occurred two years later. In all cases Mugesera was represented by Quebec lawyer Guy Bertrand.
The decision of the Federal Court of Appeal was later overturned by an 8-0 decision of the Supreme Court of Canada on June 28, 2005, which upheld the original deportation order. The deportation was delayed because of concerns about the possible use of the death penalty in Rwanda, Rwanda abolished their death penalty in 2007. Mugesera then began fighting his deportation on the basis of fears he would be tortured in Rwanda. As Canada would be reluctant to deport someone who could face torture, Kigali offered Canada "diplomatic guarantees" about the treatment of Mugesera.
On January 23, 2012, a Quebec Superior Court judge rejected Léon Mugesera's bid to avoid deportation. Mugesera was deported via Montreal's international airport the same day by 4 PM.
On April 15, 2016, Mugesera was sentenced to life in prison by a Rwandan court.
