What Is OREA Form 510?
It's an OREA standard form (not a government form) used in commercial real estate transactions in Ontario, Canada. It contains vital details of an offer to lease a commercial property: landlord and tenant information, as well as proposed terms and conditions. Once the landlord accepts the tenant's offer before the irrevocability deadline and the acceptance is communicated to the tenant, Form 510 is a binding agreement to enter into a commercial lease on its terms. The landlord then prepares the formal lease at the landlord's expense; that later step does not make the accepted agreement any less binding. You can find the OREA Agreement to Lease, Commercial PDF in PDFLiner's catalog of pre-formatted forms. The blank on this page is Form 510 Revised 2020; OREA has since revised the form (a Revised 2024 edition is in use).
Key components of OREA form 510
The document features the following crucial elements:
- Landlord & Tenant Details. Their full names and contact information.
- Detailed Property Portrayal. Area, floor and municipal address, with a plan attached as a Schedule.
- Offer Terms. Lease price and periods.
- Conditions. The form has no pre-set financing or inspection conditions; such conditions can only be added as extra provisions or Schedules.
- Key Dates. Lease commencement and termination dates, and the irrevocability date by which the offer must be accepted or it becomes null and void.
- Signatures. This confirms that both parties agree with the offer's terms.
How to Complete OREA Agreement to Lease, Commercial
If any part of the form is unclear, get professional advice before you sign. Below, we've provided the 10 steps to follow for completing this form via PDFLiner.
- Log in to PDFLiner and launch the needed file.
- Enter tenant and landlord details accurately.
- Provide the premises' area, floor and municipal address, and attach the plan as a Schedule.
- Complete the lease term (commencement and termination dates), the fixed minimum rent for each period and the day it is payable (rent is payable plus HST), and the deposit: the amount, when it is delivered, the Deposit Holder and the months' rent it will be applied against. Then tick one Services box, and tick the Additional Rent box if the tenant will also pay a proportionate share of the landlord's costs of maintaining, operating, insuring and repairing the property (including realty taxes): the fixed minimum rent is not necessarily the tenant's total cost.
- Add any conditions, such as financing or inspection, as extra provisions or Schedules (the form has no pre-set clauses for them).
- Complete the irrevocability clause: who the offer is irrevocable by (Landlord or Tenant) and the exact time (a.m./p.m.) and date until which it stays open; if it is not accepted by then, it becomes null and void. A signature alone does not communicate acceptance: the Notices clause treats a notice of acceptance as given when it is delivered to the Address for Service or sent to a fax number or email address provided in the form, so deliver the signed acceptance before that deadline.
- Include any special conditions or requests.
- Fill in agent details with maximum accuracy.
- Double-check all entries to make sure everything is correct.
- The tenant signs the offer; the landlord signs to accept it within the irrevocable time (or signs back changes for the tenant to accept).
