The unidentified man, 53, his wife, 45 and four alleged employees were charged this week 18 months after police received a tip about the operation from an informant, the Winnipeg Free Press reported Thursday.
Police kept the suburban house under surveillance for 13 days before executing a search warrant June 24 and found several rooms appeared to be geared to the retail sex trade.
Court documents allege the mother went by the name of "Sinful Sydnee," and one 55-year-old man told police he had paid her $200 an hour to be a dominatrix in the home in four visits since February.
In a court affidavit, Detective Brad Jones wrote the female informant was very concerned for the young girl after hearing the mother and daughter talking.
"She (the informant) has overheard her telling her daughter that it is OK for women to have sex for money, that it is normal, and talking about another woman giving her husband oral sex," Jones wrote.
The other four charged faced prostitution charges, the newspaper said.
No court appearance dates were published.
