Gagandeep Sidhu was initially charged with first-degree murder in the March 2013 death of his wife Monisha.
Police said the two were arguing in their vehicle and the woman got tangled up in her seatbelt when she tried to get out.
She was dragged for a few hundred metres, but managed to fee herself and run away.
But Sidhu caught up to her and strangled her.
He pleaded guilty to second-degree murder.
Sidhu’s lawyer, Alain Hepner, says it appears his client is suffering from some psychological issues, but that doesn’t exonerate him.
