Customs clearance is the wild card — a parcel can clear in a day or sit for a week, and that variability is usually what stretches a delivery window. Made-to-order upholstery adds its own lead time on top, regardless of border crossing. Ordering from a brand's Canadian site (like westelm.ca or wayfair.ca) usually means faster, more predictable delivery than buying from the US site and shipping north, because the order ships from within Canada and skips the border entirely.
