IRCC won’t need to wait till everyone is vaccinated. They may resume the process as soon as the situation is better. IMO.There's actually gonna be a reduction of Pfizer vaccine shipments in the next couple of months so vaccine rollout might be delayed. And like here in Alberta, they're anticipating rollout to general public in Fall. And those working for IRCC are not really considered essential workers or frontliners so they would probably fall under the general public category.
It will happen eventually.
