This seems to be a false conclusion, most likely based on Rob Ford having coached at a Catholic high school. There does not seem to be any actual evidence of him, his siblings or his parents being Catholic. On the other hand there is considerable evidence to the contrary - e.g., none of Rob and his siblings attended Catholic schools, neither Rob nor Doug were married in Catholic ceremonies (Randy has never married; I can't find any info on Kathy is this regard), Rob's and his father's funerals were not in Catholic churches, neither Doug Sr. nor his father are buried in a Catholic cemetary, etc.
