Johnson Aziga, the first person in Canada convicted of murder through HIV transmission, has been declared a dangerous offender.
With the designation, the Hamilton, Ont. man can be jailed indefinitely.
The Ugandan immigrant was convicted in 2009 of two counts of first-degree murder, 10 counts of aggravated sexual assault and one count of attempted aggravated sexual assault.
The Crown argued Aziga should be labelled a dangerous offender because of his abnormally high libido and because he has shown little remorse.
Aziga "represents a gamble on the safety of the women in this community." Ontario Justice Thomas Lofchik said in a 50-page decision.
After the decision, Aziga, 54, said he wanted to renounce his Canadian citizenship and serve his time in Kenya or Uganda.
Aziga, a father of three, admitted to having unprotected sex with 11 women without telling them he has HIV, but has repeatedly said he can't know for sure that he infected any of them.
Two of those women later died from AIDS-related cancers. Five others have tested positive.
In court on Tuesday, Aziga said he intended to use condoms but didn't because the women insisted.
Previously, he accused the jury that convicted him of racism and blamed health officials for not instructing him on how to properly disclose his HIV status.
He was diagnosed with HIV in 1996 and ordered by public officials to disclose his illness to sexual partners.
Aziga was a highly-educated employee of the Ontario government at the time of his arrest.
Aziga has been in custody since 2003.
