Peel Regional Police were called to an apartment at 480 Lakeshore Rd. E. in Mississauga, where they found a "deceased female with obvious signs of trauma."
Investigators have since identified the victim as Aicha Saludares, 40, of Mississauga.
Police are now seeking a warrant for the arrest of her 39-year-old husband, Nelson Tayongtong.
Tayongtong is originally from the Philippines, but until recently was living in Mississauga.
He is described as five feet seven inches with a slim build and short, black, straight hair.
