WOW 🚨 Pay Attention To Canada Because America Is Next. QR Codes To Visit & Leave Areas Quebec: “Madeleine Island getting QR codes in order to leave and If you don't get your QR code, you will be fined” “That's the very first QR code prison here in Canada. And it is going to sweep the nation faster than you can think if people don't stand up and take a stand against these QR codes.” “It's not happening in your town yet but it most certainly will be.” “We know the government's expropriating land from farmers all over the place. We know that they are trying to make military presence and normality, so it's only a matter of time before you are trading away your information, your private information in a QR code in order to leave your town or city so that you can go to work, shop, get an education, or just plan out, visit, and travel this amazing country. Time to stand up and wake up and use your voice.”
