Edit to note: two responses "disagreeing" with me by pointing out that the BC lockdown is effectively the same thing as the California one from the perspective of economic impact. This is why I asked the question! People are being fooled into arguing with a strawman idea of "lockdown" that isn't what is actually implemented.
1. Restaurants are closed except for take-out and delivery. 2. Personal services businesses are closed. 3. Large gatherings of all kinds are banned. 4. Schools are closed.
You can still go to your office if you wish to, so long as social distancing rules can be respected (staying 2m apart). This being said, the vast majority of businesses that can have their employees work remotely are doing so, simply out of a concern for their health and wellbeing. If you have to have employees in your workplace, then there are guidelines for making it as safe as possible.
There is also extensive testing. Anyone with symptoms can be tested promptly.
Offices are voluntarily closed, as far as I can tell, not by fiat. While you're only supposed to be working at an office if you're an essential worker, the definition is somewhat loose.

"Everyone is required to stay home except to get food, care for a relative or friend, get necessary health care, or go to an essential job... If you need to get into a car or on public transportation to go for a walk or run, you’re going too far."
Generally there is sufficient distance from other people when gassing up, so that seems like a very low risk for a short period of time, compared to walking in a city.
You are also at risk of requiring ambulance transport if you do DIY work at home. So best just sit in a dark room because you don't want electricity workers to have to go to work, or Netflix employees to have to go into work, etc.
If you think a pandemic is the time to start major DIY projects then you really don't get it. You're not alone in that, but that doesn't make it smart or right.
