By assuming a multi-year sequence with uncertain dates: petition processing, visa availability for the applicable category, consular processing or adjustment, two years of conditional residence and then the removal petition.
Keep the Alberta arrangements workable for longer than expected
Hypothetical example: the couple sell the store, sell the house and rent short-term, expecting to move within the year. Each stage has its own duration and none is guaranteed. The petition is processed on the agency's current timeline.
Visa availability for the relevant category can add waiting that has nothing to do with processing speed. Consular processing or adjustment follows. Conditional residence then runs two years before the removal petition is due within a defined window.
The project has its own construction and hiring schedule alongside all of that. Keep housing, health coverage and income arrangements in Picture Butte workable well past the optimistic estimate, and avoid irreversible steps until a status has actually been granted.
