Here in Canada, rules vary from province to province. Ontario has a long list of "essential businesses" that is getting shorter daily. Canadian Tire (essentially a large hardware chain + tires and car service) has been shut down in Ontario, and they have gone online with curb-side pickup. Their website is suffering from excess traffic. They are still open here in BC.
In BC, some types of businesses where social distancing is impossible have been shut down (hairdressers, yoga studios, gyms, tattoo parlors, most dentists, eat-in restaurants, bars, etc). Also, gatherings of people over a certain number (I think it's currently 50) have been outlawed. Most other businesses are allowed to open but have operate in a safe manner, and our "accepted distance" is 2m (a little over 6 feet), though in some cases it's more aspirational than enforced.
I live in a small tourist town, and businesses have reacted differently to the restrictions. We walked around downtown, which is now practically deserted and read the notices: many businesses are closed, some are by appointment only, some have drastically reduced hours, some allow only one customer in the store at a time, etc. The large grocery stores and drug stores are still open, and I am afraid that when this is all over, we'll all be shopping at WalMart and SuperStore cause those are our only choices.
We are getting take-out food from a small local restaurant, cause we want it to be there when we can finally "dine out". I went to the local sewing store during one of the two mornings a week that it's open; I told the proprietor what I was there for; he put on his mask and came out from behind the desk to get the item and confirm that it was what I wanted; I paid (by tapping my VISA card) and I left. Again, I want them to survive, as they always have excellent suggestions for what I need, often items I didn't even know existed.
There are special programs for the suddenly unemployed and under-employed. Those are federal. They are essentially handing out money based on self-reporting, but will verify eligibility and claw it back from those who over-collected come tax time in April, 2021.
