How soon can one reenter Canada after a 2-year visit?

[soucal]

My mom has held a 5-year visitor's visa (not a Supervisa).

Per her visa requirements, she would enter Canada to stay with me for 6 months and then would leave Canada for 6 months.

The most recent time she visited me, I extended her stay in Canada by another 1 1/2 years, for a total of 2 years.

Now, after her 2-year stay in Canada, how long does she have to stay outside of Canada? Six months as always? Or same length of time she spent in Canada, 2 years? Official proof would be appreciated.

Thanks!

There's no black and white answer since whether she is allowed back into Canada and for how long is ultimately up to the CBSA officer she encounters at the border. Having said that, given she's been in Canada for 2 years, I would stay out for 8 months before attempting another long visit.
