One option is the SIMs and phones available from Petro Canada Mobility (Petro Canada is a large gas station chain here) -

Conveniently, there is a Petro Canada Station right at the airport and according to the link above they do sell the service. Alternately, you can buy a SIM online and ship it to you, or to your hotel.
The other option is "Speakout" which is sold by the 7-11 convenience store chain:
http://www.speakout7eleven.ca/
Same deal - Either buy from the store or order online.
Both services are Mobile Virtual Network Operators (MVNOs) operating on the network operated in Canada by Rogers Mobility.

Are you asking if there is WiFi at YVR? The answer is yes - It's ubiquitous and fast.
