If it not mandatory how are the OPP and city police issuing penalties between $1,000 and $6,000?  I just spoke to our mayor and posed the question of voluntary or mandatory, he said it is enforceable as per the Premier of each province (thus mandatory). COVID-19 and the Emergencies Act (Canada). As we move deeper into the COVID-19 pandemic in Canada, provincial, territorial and municipal governments are now using legal rules to impose self-isolation and social distancing measures for the common good of preventing community transmission of the virus. The narrative in daily updates from government leaders and public health officials has shifted away from encouraging voluntary practices and more towards invoking command and control, as evidence mounts that voluntary suggestions are not being followed. Command and control is, however, largely going to be a general deterrence measure because actual enforcement in individual cases will be very difficult and resource intensive (hence why some jurisdictions, such as the State of Oregon, are encouraging citizens to help with enforcement by reporting violators of public health orders). All of this underscores the fact that we are truly in the midst of a socio-economic crisis, and has led to suggestions (e.g. see here and here) that federal cabinet issue a proclamation of national emergency under the Emergencies Act, RSC 1985, c 22 (4th Supp) and exercise the powers granted thereunder.
