I know you are looking for a bit more specific advice, but I think you generally seem to be on the right track. As others have said, you seem to be dealing with this in a classy and fair way, at least coming across on a couple of posts. If that is how you are coming across to them in "real life", kudos to you.

1) I really like the above suggestion of just putting a 2-second list together of services, like cleaning companies, moving, close restaurants, grocery stories, etc etc. Especially if they are coming from out of town, that would likely be a huge help. You don't have to do it, but it would be very considerate of you.
2) Have you called Landlord-Tenant;s? You likely already have, but why not call Service Alberta and give the 2 second overview and see what advice they would have? Would give you more of the technicalities etc, or be able to direct you to resources that could:
