A cross-province move has two buildings, two sets of rules, and one truck trying to satisfy both within a delivery window. This is where otherwise-smooth moves fall apart, because the access requirements are often invisible until you ask.
Multi-unit buildings — condos and many apartments — commonly require residents to reserve the service elevator for a move, frequently a week or two in advance, and to provide a refundable security deposit and sometimes a move fee. As a Toronto condo moving guide details, bookings come with strict time slots, mandatory use of the loading dock, rules about where the truck can park, and financial responsibility for any damage to common areas. Many buildings also require a Certificate of Insurance (COI) — proof of the moving company's liability coverage — naming the building before they will approve the booking.
Now layer the long-distance reality on top. Your building gives you a fixed two-hour elevator slot on a Tuesday. Your mover gives you a delivery window of Tuesday to Friday. Those two facts do not automatically agree, and reconciling them is your job, not the building's. The fix is sequencing: ask the mover for the COI early, confirm both buildings' access rules and available time slots before you finalize anything, and tell the mover about every access constraint — narrow streets, no loading dock, low parkade clearance, long carries from the truck to the door — so it does not surface as a surprise accessorial charge or a missed booking that forces a rebooking.
Do the same diligence at origin and destination. A delivery that arrives to find no elevator booked, a blocked dock, or a truck that cannot legally park can mean waiting, rescheduling, or fees — the precise outcome a little upfront coordination is designed to prevent.
