Here's how to figure out how much OAS she was getting:
https://www.canada.ca/en/services/benefits/publicpensions/cpp/old-age-security/benefit-amount.html  

So, basically, other than for the exceptions listed, presumably related to legislative changes in 1952 and 1977, to qualify for full OAS at one's age 65, one has to have not lived outside of Canada for seven or more years. For every year lived outside of Canada after those seven years, one's OAS pension is reduced by 1/40th.

So, moral of story: stay in Canada for substantially all of your life.

Cheers,
Doug
