RCMP say the senior was allegedly stabbed early Saturday morning when the intruders burst into his home on the Buffalo Lake Metis Settlement northeast of Edmonton.
The suspects allegedly broke his nose and elbow when an attempt to steal his car was thwarted.
Mounties say the invaders then went to a second home where they convinced a 70-year-old woman to let them in to use the phone before they allegedly assaulted her and stole her vehicle.
Police are looking for Dakota Clane Boudreau, who is 20, and a 41-year-old man, David Norman Boudreau.
They say the pair may be driving a grey-coloured 2005 EXT Cadillac Escalade with Alberta licence plate HMU-232.
