Canadians are travelling to Cuba in surprising numbers to sexually exploit young people trapped in the socialist country’s underground sex tourism industry, a joint investigation by the Toronto Star and El Nuevo Herald, the Spanish-language sister publication of the Miami Herald, has found. Havana’s conspicuous scenes of street-level prostitution are the public face of a hidden, sordid trade in children as young as four. Many prostituted children in Cuba are second- or third-generation, following in the footsteps of sex-worker mothers to earn money for families complicit in their exploitation. Cuban authorities deny the problem. And Canada’s lax oversight suggests any self-proclaimed moral obligation to protect children from abuse stops at our own borders.
