Martin Billings is asking that anyone who has seen his son Tom to come forward.
The recent university graduate was last seen on Nov. 25 before making his way to North Vancouver's mountains, presumably to hike for a few hours.
The 22-year-old man was stopping over in Vancouver for a few days as part of a North American vacation tour intended to end on Dec. 7 in New York.
He hitchhiked and bused throughout the United States before hitting British Columbia and found accommodations in East Vancouver via couchsurfing.org.
Tom Billings had just finished applying to various universities to get a position as a post-graduate researcher and used the spare time before his interviews to vacation.
