Mike Duffy trial: Crown expected to stay focused on alleged dog show expense

The Crown in the Mike Duffy trial in Ottawa is expected to resume its focus today on the suspended senator's travel expenses, including his claim for a trip to Peterborough, Ont., in 2010 that included a stop at a dog show.

The Crown has accused Duffy of filing expense claims for events not related to parliamentary work functions. This includes $698, which the Crown alleges was for a trip he took with his wife to a dog show in July 2010 to buy a Kerry blue terrier.

The trial, in its 20th day on Wednesday, began April 7 in a provincial court. ​Duffy has pleaded not guilty to 31 charges of fraud, breach of trust and bribery related to expenses he claimed as a senator and later repaid with money from the prime minister's former chief of staff, Nigel Wright.

On Tuesday, court heard from Louise Lang, secretary of the Kerry Blue Terrier Club of Canada, who testified that she briefly met with Duffy at that show. She also testified that a Kerry blue terrier breeder from New Brunswick was at the show at the same time as Duffy.

But Duffy's lawyer, Donald Bayne, questioned Lang's memory of the events of that day. Lang admitted that when she was interviewed by the RCMP in 2013, she couldn't recall the exact year she had met Duffy. She also said she told the RCMP that she couldn't remember if Duffy's wife was there with him and that Duffy had picked up a dog at the show.

However, Bayne said Duffy never purchased a dog at the show, but instead bought one from the New Brunswick breeder in that province in January 2011.
