looking for my grandfather

Hi, I am looking for my grandfather who emigrated from norway to canada in the early 1900, I only have some infos on him. His name is Peter Olsen he was born in olso in december of 1886, was baptized in feb of 1887. His father's name was Peter Olsen and his mother's name was Olga Pedderson or Petterson. It would seem that he emigrated on the 10 of april 1904. If someone could help me I would appreciated a lot. Thank[:)]
