In that case he's going to have a pretty hard time returning to Canada. His only hope is to fly to the US and then to try to re-enter Canada through a land border using a private vehicle. Given how long he has been outside of Canada, there's a very high chance he will be reported at the border for failing to meet the residency obligation. If this happens, he will have to appear at a hearing and should expect to lose his PR status officially and be ordered to leave Canada. If he manages to re-enter Canada without being reported, he will have to live in Canada for 2 years straight without leaving before he will be able to renew his PR status. During these two years, it may be difficult to obtain health care coverage depending on what documents he has. He also won't be able to sponsor anyone for PR during these two years.
So the short answer is that it will be very difficult for him to keep his PR status. His only option for coming to Canada is to fly to the US and to try to re-enter Canada by land.
