Albertans would keep their Canadian passports after independence.
Stated by: Alberta Prosperity Project
Summary
This is plausible but not guaranteed. Canada allows dual citizenship and rarely revokes it, and the peaceful split of Czechoslovakia let many people sort out citizenship over time. Whether Albertans kept Canadian citizenship would still depend on a negotiated agreement rather than an automatic right, and constitutional experts warn there are no guarantees if the split turns hostile.
Evidence
Canada allows dual citizenship and does not strip Canadians of citizenship when they acquire another; citizenship is lost only through formal renunciation, which is why advocates argue Albertans would keep their status. Whether that survives a split still turns on negotiation, not this rule.

When Czechoslovakia split in 1993, all citizens automatically became citizens of one successor state based on residence and ties, with a window to claim the other, an arrangement set by negotiation and domestic law.

Constitutional experts caution there is no guarantee Albertans would retain Canadian citizenship, particularly if separation negotiations became acrimonious.
