Westdale runs on the McMaster calendar. Late August and early May are the busiest weeks of the year here, and that is exactly when cardboard is hardest to find and every mover is booked. Bins are reserved ahead for a specific date, so the supply problem disappears.
The housing is mostly semis, converted student houses and low-rise apartments around Sterling, Emerson and Marion. Rooms are small, staircases are shared, and several households often move on the same day from the same street.
Parking is the other constraint. Permit zones around campus and Westdale Village fill quickly in move-in week, so the fewer trips you make with a vehicle, the better.
