Neither was I. From what I was told they were questioning why he was on the street so late during the pandemic.
For whatever reason they wanted to take him back to their station unless he could prove he was an essential worker.
Interesting. This, from the TPS website:
On March 31, 2020, the Government of Ontario made changes that require an individual to identify themselves at the request of a police officer, if there are reasonable grounds to believe the individual is violating an emergency order.
These emergency orders include a prohibition on all organized public events or social gatherings of more than five people and the closure of the following establishments:
All facilities providing indoor recreational programs
All public libraries
All private schools as defined in the Education Act
All licensed child care centres
All bars and restaurants, except to the extent that such facilities provide takeout food and delivery
All theatres including those offering live performances of music, dance, and other art forms, as well as cinemas that show movies
Concert venues
All City-owned playgrounds, sports fields, basketball and tennis courts, off-leash dog parks, skateboard and BMX parks, picnic areas, outdoor exercise equipment and other parks amenities, as well as parking lots attached to its parks system, will be closed effective immediately.
City of Toronto staff continue to lead with monitoring and providing information and education to non-compliant individuals and businesses. The Toronto Police Service will also conduct proactive enforcement, when necessary. This includes visiting establishments that have not complied with the provincial directive and, under each circumstance, using officer discretion to determine the proper action.
There are various options of enforcement, ranging in severity from a $750 ticket to a summons, which upon conviction can result in fines from $100,000 for individuals to $10 million for businesses, to arrests and criminal charges of Obstruct Police.
You are required to identify yourself once the officer has reasonable grounds to lay a charge so the officer can properly issue you a ticket or summons, whichever they deem necessary.
So it seems that if you are found in violations of a specific order (which I don't believe simply driving or walking around is) and you fail to identify yourself you could be arrested for Obstruct Police (criminal). I can find no arrest authority for violating an order itself, and if what you are doing doesn't violate an order, then a charge of Obstruction would be invalid.
