Thanks for link.
The people I was speaking with told me that PR RO aside, immigration officers can simply 'refuse' entry as you had been away for too long. The case I heard involved someone denied entry into Canada when they tried entering 8 months 3 weeks after initial landing date.
What do you make of this?
That is
not possible, unless they were unable to satisfy the CBSA officer of their identity. A PR, regardless of their compliance with the RO has the RIGHT to enter Canada at the border, (not withstanding a very small number of
very serious circumstances, under which the PR is actually arrested at the border, and not just turned away.)
