Alberta separation and citizenship

Albertans could still freely live and work anywhere in Canada after independence.

The right to move to, live in and work in any province comes from section 6 of the Charter, and it belongs to Canadian citizens and permanent residents. If Alberta became a foreign country, its residents would no longer automatically hold those Charter rights, and whether they kept them would depend on whether Canada agreed to let Albertans retain Canadian citizenship and on any mobility agreement negotiated between the two countries. The Alberta courts reviewing a proposed independence referendum noted that this is contingent and cannot be known in advance. Presenting continued free movement as a certainty is misleading.

Albertans would keep their Canadian passports after independence.

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.
