The dogs were discovered in mid-September on a rural property in western Quebec.
The operation was described as the largest dog rescue in Canadian history.
The canines were living in poor conditions without sufficient food and water.
They range in age from puppies to fully grown dogs and different breeds are represented.
Humane Society International/Canada will put the dogs up for adoption after reaching a deal with ANIMA-Quebec, a provincial government agency.
The discovery of the dogs was just the latest in a series of disturbing animal-abuse cases in Quebec that have made headlines in recent years.
The province has long been considered the puppy mill capital of North America, with an estimated 800 unregulated breeding operations in Montreal alone.
In August, nearly 40 malnourished huskies were found chained to trees on a property northwest of Montreal.
Reports in May of animal suffering at Montreal's privately held Berger Blanc pound also shocked many across the country.
Videos of cats and dogs suffering, as well as images of questionable euthanasia practices documented in a Radio-Canada report, prompted widespread criticism.
Quebec was named ''the best province to be an animal abuser'' in the 2011 annual report prepared by the U.S.-based Animal Legal Defence Fund.
