Alberta has now filed its factum in the Senate reference. You can view it here.
In short, Alberta, which of course is so far the only province to conduct Senate elections, believes Parliament can unilaterally legislate
both consultative elections and term limits and that the Senate can be abolished with the agreement of seven provinces representing 50% of the population. That puts Alberta in agreement with the federal government’s position.
Update 3:31pm. I misread. Alberta believes provincial participating is required to legislate term limits.
