The guidance from authorities to stay home except for essential errands, and to keep six feet apart from others, is strong advice, not the law.
Some of the social distancing rules do have the force of law, however.
The province’s public health orders are examples. These include the order prohibiting gatherings of more than 50 people, and an order requiring restaurants and pubs to take measures to physically distance groups of patrons. The latter order, which was updated on July 31, 2020, spells out how establishments must keep two metres between groups of patrons and get contact information for one member of every group (among other measures).
So far, though, in guidance to its bylaw officers, the province is focusing its efforts on monitoring and education. The officers (and police) are not empowered to fine or detain people in enforcing these orders. Vancouver’s bylaw officers are similarly focused on monitoring and educating to date.
One rule has more severe penalties if you don’t follow it. If you’ve just returned to Canada from abroad, you must isolate or quarantine, depending on if you have symptoms. (The federal government website explains the difference.) You can be fined or jailed for failing to follow this order.
