Workers exempt from the federal Quarantine Act do not have to create a self-isolation plan, this includes Truck drivers.
BC Government announced new measures to boost COVID-19 response. “Effective immediately, international travellers (including from the United States) coming to the province are required to provide a self-isolation plan before or upon arrival to B.C., regardless of their point on entry to Canada.” This includes essential service workers who must travel across the border for work, such as transportation workers. However, they are only expected to implement their plan if they develop symptoms. Press Release: https://news.gov.bc.ca/releases/2020PREM0019-000657.
