Richard flew in last night on WestJet from Orlando.  When he arrived at YVR his temperature was not taken.  When he went through Customs and Immigration he wasn't asked any questions or given any verbal information on the virus.   He was not handed a pamphlet on what to do upon arriving in Canada.

This is on the BC Center for Disease Control website:

Airport Screening

The federal government is doing several things to inform and screen travellers at the airport. It has set up a system at international airports to find out people who have been to Hubei, Iran or Italy to confirm where they have travelled to and if determine if they feel well or unwell.
