Buying pre-construction at Addison Residences begins with registering for first access, which typically means receiving early information on floor plans, pricing, and release phases before broader sales. Buying early in a release can matter because inventory and pricing often change from one phase to the next.
Deposits on new condominiums are usually structured in stages spread over time rather than paid all at once, with instalments tied to signing and construction milestones. Your agreement will also outline interim occupancy — when you can move in and pay occupancy fees before the building registers — followed by final closing, when title transfers and your mortgage begins.
In Ontario, new condominium purchases include a 10-day cooling-off period under the Condominium Act, during which you can review the disclosure documents and your agreement, and cancel if you choose. Specific deposit amounts and schedules will be confirmed by the builder.
Prices at Addison Residences start from $589,990 CAD. Pricing can change between release phases, so current figures should be confirmed with the builder.
