Is it legal for a store to refuse my cash?

More businesses are going cashless during the COVID-19 pandemic and are asking customers to use debit, credit or app payments as a precautionary measure.

But some readers, such asSamar D., are asking if it's legal for a retailer to reject payment in cash.

The short answer is yes, astore can refuse to take cash. But it's a little more complicated than that.

The Bank of Canada says it's up tosellers to determine what kinds of payment they will accept for transactions, and there is "no law" that would require anyone to accept bank notes or any other form of payment for a commercial transaction.

However, in certain circumstances, refusing to take cash in a store may actually violate provincial human rights codes.

Michael Bryant, executive director of the Canadian Civil Liberties Association (CCLA), warns that a store's no-cash policy could inadvertently discriminate against seniors, people who are disabled, impoverished or people who just don't have credit or debit cards.

"Not only does this hurt their ability to transact, but it threatens their food security," Bryant said.

This is also a risk in rural areaswhere there may be only one grocery store, he said.

"So [retailers] need to use their discretion."

How to handle cash during the COVID-19 pandemic

With recent efforts to limit the spread of germs and reduce contact, a look at how to handle cash during a pandemic.

What can I do if a store won't take my cash?

Not being able to pay for food and other necessities adds "another layer of anxiety to an extremely stressful existence," said Bryant.

So if you're told you can't pay with cash, he said it's worth contacting your provincial human rights commission or the CCLA.

"Somebody needs to tell that store owner that they need to develop a system for the rare cases in which cash is the only option," he said.

And even ifstores saythey prefer plastic only, it's worth asking if they can make an exception.

Some retailers like the Metro grocery chain in Ontario and Quebec say they're encouragingcustomers to usecards, but they'll still take cash if it's the only option.

Why is there such a fuss over accepting cash?

While there is no specific danger inusing cash as opposed to any other sort of physical interaction, health authorities around the world are urging people to keep touch to a minimum.

That would include handing over bills and coins from one person's hand to another.

But there is something else you should be thinking about when it comes to payment, said Colin Furness, an infection control epidemiologist and assistant professor at the University of Toronto.

"The buttons on a credit/debit machine would be riskier than cash, because those same buttons are being pressed by the tip of oily fingersand lots of themconstantly," he said in an email.

"It's the tip of the finger that then goes in the eye, noseand mouth," he said. "Tap to pay would be safest."

Then there's all the other things you're touching: "Merchandise, counters, door handles, and we can add cash to the list," Furness said. "It doesn't represent a new or increased risk. It's one of a long list of reasons to carry hand sanitizer and use it."

And as always, no matter what, physical distancing, good hand hygiene and being aware of what you're touching are the best things you can do to keep yourself safe.

How long does the virus laston bills and coins anyway?

We know the novel coronavirus lasts on different surfaces for different amounts of time, but we don't know exactly how long the virus could last on different types of money.

According to that research, it could last longer on coins than bills.

"Coronavirus will last up to three days on a hard metal or plastic surface at room temperature," said Furness, referring to a study done in April.

The softer the surface the shorter period of time the virus lasts, he said.And though the virus starts to degrade or break downright away, it can take up to three days for it to be totally gone.

If you're still not confident, Furness recommends letting your money sit for a while.

"Assume three days, and you are very safe," he said. "Even one day would be low risk. I wouldn't bother trying to disinfect money.I'd let it sit instead."

But if I want to disinfect my money?

If cleaning your cash makes you feel better, the Bank of Canada says soap and water will do the trick on polymer bank notes because they're resistant to moisture.

But don't use disinfectant wipes or other products containing bleach or rubbing alcohol. The central bank says these substances can damage the notes to the point where they may not be recognizableas legitimate money.

It's also a bad idea to wash older paper bills which, unlike polymer notes, aren't resistant to moisture.

As for debit and credit cards, a disinfecting wipe or cotton pad with alcohol will work as will a non-abrasive soap mixed with water.

A spokesperson from the Royal Bank of Canada says it won't damage the magnetic strip or the chip.
