The three men, aged 19, 21 and 22, were arrested Friday night after the RCMP received a call from a residence on Church Road at 10:45 p.m.
Three males, disguising their faces, had entered the residence without consent and assaulted a man. They used an irritant spray and fled with a quantity of cash.
With the assistance of a police service dog, the suspects were tracked to a residence on Marshall Lane and arrested.
The victim was transported to hospital with minor injuries and later released.
The NorthEast Nova Major Crime Unit has been called in to assist with the investigation.
