I have gotten different answers from CBSA and online sites. Does Canada do 6 months in a calendar year or rolling year? I thought it was a calendar year and I overstayed from August 2019 to June 2020 by 5 days if it is a rolling year, as I quarantined there before heading back to the USA. I called border agency and was told 6 months...then it is reset for the next visit! I wasn’t going to tell the person they were wrong...
