A few things reliably shorten a moving day, and none of them cost anything.
Confirm parking. In much of Montreal the difference between stopping outside the door and carrying everything sixty metres is a permit or a neighbour moving a car. Tell us where the vehicle can realistically stop and, if a permit is needed, arrange it in advance.
Book the lift if there is one. In buildings that require it, an unbooked lift can cost an hour of crew time before anything is even loaded.
Have boxes closed and labelled by room. We are happy to work around an unfinished pack, but a crew standing by while a cupboard is emptied is billable time doing nothing.
Set aside what you want with you rather than in the vehicle. Documents, medication, chargers, keys. It is the single most common thing people wish they had done.
