 Perri specialized in exporting liquor from old Canadian distilleries, such as Seagram and Gooderham and Worts to the United States, and helped these companies obtain a large share of the American market — a share they kept after Prohibition ended in Ontario in 1927, and the United States in 1933.He has also been linked as a distributor of Canadian whisky to New York City's Frank Costello and Chicago's Al Capone; however when Capone was asked if he knew Perri, he said ""Why, I don't even know which street Canada is on,"" however other sources claim that Capone had certainly visited Canada, with one stating that he maintained some hideaways north of the border.Perri also sold trainloads of liquor into Detroit and Chicago through Niagara Falls, Ontario and Windsor, Ontario.
