Turns out that WEF darlings Justin and Chrystia were supposed to be the tip of the spear for piloting the WEF digital ID system. So, faced with the threat of peaceful truckers occupying Ottawa and making like Canadian Geese with their horns, they decided to just go all the way and weaponize the banking system to meet the enormous threat to Canadian national security posed by the truckers. Well, that did not turn out quite as planned.
Apparently, when those holding both large and small bank accounts realized that TD Bank and other large Canadian banks were no longer a safe harbor, they decided to withdraw their funds. Oops.
