Local information

Getting here from the airport

There are good public transport links from Vancouver airport to the main UBC campus. From Vancouver airport, take the Canada Line train (northbound, the only possible direction from the airport station). Change at Oakridge–41st Avenue station to the westbound R4 bus line (this requires crossing 41st Avenue to reach the bus stop on the north side of the street). Both the train and the bus come very frequently during the day, decreasing to about every 15 minutes at night. The entire journey requires only one ticket, which should cost about CA$8 (around CA$3 for the standard fare, and a CA$5 surcharge for journeys from the airport station). The duration of the trip should be about 1 hour.

It is also possible to take a taxi, which will take about 30 minutes and cost around CA$35.

Housing Options

Housing at UBC expensive, although the exchange rate between the US Dollar and the Canadian may go some way toward offsetting this for US-based visitors.

  • West Coast Suites are the on-campus hotel option.
  • St John's College is a residential college on campus with a limited number of guest rooms. Please be sure to mention the Cascade Topology Seminar if attempting to book one of them.
  • The Carey Centre is another on-campus option.
  • Off campus options are also available. There is an excellent bus network in Vancouver, and UBC is around 40 minutes by bus from downtown Vancouver.
