Without this person's consent, you can't.
Requests for personal information that is not the requester's must include signed, recent (less than one year old), written consent from the individual to whom the personal information belongs.
In theory it might be possible to get a court order to release this information to you. I don't know under what circumstances that might be granted; I suspect it'd be very rare. But you'd have to consult a lawyer about that. If this person hasn't been convicted of anything in Canada, then presumably he still has his usual rights to privacy under Canadian law.
If he's wanted on suspicion of some crime, the police might be able to access this information to help find him; but you are not the police.
