Mean contact rate during four escalation phases of physical distancing measures. We considered four phases of escalation in Ontario: phase 0, monitoring and international travel advisories (until Mar 13); phase 1, public school closure (Mar 14–17); phase 2, physical distancing advisories (Mar 18–23); phase 3, closure of non-essential workplaces (Mar 24–May 16). The contact mixing matrices are constant for phase 0, 1 and 2 and the contact mixing is modelled as time-dependent for phase 3. (A) The mean contact rate from phase 0 (12.27), 1 (11.42) to 2 (10.92) including the setting breakdown; (B) The time-dependent mean contact rate by setting for phase 3
