Unvaxxed people will be denied entry to big-box retailers unless they shop for food or visit the pharmacy. Even then, they will be under the supervision of an employee (to make sure they don't buy anything else). 

Quebec expanded the vaccination passport to enter all businesses with surface areas larger than 16,000 sqft or more -- except for groceries and pharmacies. The new measure was announced on Sunday night. 

For pharmacies located in Walmart and other big-box retailers, an unvaxxed must be "accompanied at all times during his or her travels by an employee of the business, the pharmacy or any other person mandated by them for this purpose" the measure reads. 

"This person may not purchase products other than those related to the pharmaceutical service they are receiving," it also said.
