"Based on DBS samples collected between April and August 2022, nearly all Canadian adults (98.1%) had antibodies against SARS-CoV-2 during that time. These antibodies were acquired through either vaccination, a previous infection, or both. Over this period, 53.9% or about 16.4 million Canadian adults living in private dwellings had antibodies indicating a past infection, which is more than 20 times higher than the 2.6% observed from November 2020 to April 2021."
