About Devron Developments and Dorsay Development Corporation
1 Marlborough is a joint effort by Devron Developments and Dorsay Development Corporation, two builders active in the Toronto market.

Buyers can expect further project details to be confirmed by the developers as the release progresses.
Buying pre-construction at 1 Marlborough
Buying pre-construction at a project like 1 Marlborough usually begins with registering for first access, which can put you in line for early information, floor plans, and pricing before wider release. Buying early in a release can matter when a limited number of larger suites and penthouses are involved.
Deposits on new condos are typically staged over time rather than paid all at once, spread across a series of milestones set by the builder. After construction, buyers often take interim occupancy — moving in and paying an occupancy fee — before final closing, when the unit is registered and title transfers. The specific deposit structure for this project will be confirmed by the developer.
In Ontario, buyers of a new pre-construction condominium have a 10-day cooling-off period under the Condominium Act, during which you can review the agreement and disclosure materials and cancel if you choose. This is a general overview and not financial or legal advice; review all documents carefully before committing.
