Hundreds of women were murdered on Terrazas' watch.

Demonstrations in Montréal, Ottawa and Mexico were held today to express opposition to the presence of Francisco Barrio Terrazas, Mexico's new ambassador to Canada.

[He] assumed the cushy diplomatic posting on February 26th, 2009. He had previously served as mayor of Ciudad Juarez, known as the Murder Capital of North America, and later as governor of Chihuahua state.

Representing the regime of Felipe Calderón in Canada is a man who governed a city where more four hundred women have been killed since 1993. Many of the women killed were sexually assaulted first. Barrio Terrazas refused to call for an investigation until 1998.

"We can't accept that Canada, a model country that's culture is based on the respect of human rights and rule of law, could shelter a person who tolerated the murder and rapes of women and girls," reads a statement concerning Barrio Terrazas' appointment from May our Daughters Come Home, a women's group based in Juarez.

In Montréal several organizations, including la Fédération des femmes du Québec released statements protesting his appointment and deploring his complicity in allowing the murders of women to continue unchecked and undermining investigations into the criminal activities that have brutalized women in Ciudad Juarez.
