A South Shore man has been ordered to pay child support for four children even though he found out recently that three aren't his.

The man requested DNA tests after he separated from his spouse following 15 years together. It turned out that only the youngest child was his biological offspring. The others were fathered by three other men.

The man has told the Journal de Montreal that those men should be on the hook for child support.

However, the courts have ruled that the man acted as the father of the family in every other way for years, so his financial support of all four children should continue. His payments come to about 900 dollars a month.
