Why was my CPP and OAS reduced as of January 2021 - my husband was also reduced.

Hi,

My expertise is limited to U.S. Social Security benefits, and there haven't been any regulatory changes that would explain a decrease in your U.S. benefits. Social Security generally sends a notice in the mail explaining any changes in a person's benefit rate, but if you don't get a notice you'll probably need to call Social Security to ask for an explanation.

Best, Jerry
