Uploading Ontario standard lease

OntarioLandlord can extract data from your signed Ontario Standard Lease (OSL) PDF, saving you time on data entry.

What is the OSL?​

The Ontario Standard Lease is the mandatory lease form for most residential tenancies in Ontario. It includes standardized fields for:

  • Landlord and tenant names
  • Property address
  • Rent amount and due date
  • Lease start and end dates
  • Included services and utilities

Uploading your OSL​

Step 1: Navigate to upload​

  2. Click Upload OSL

Option B: During Onboarding

  • Select "Upload Existing Lease" path

Step 2: Select your file​

  1. Click Choose File or drag and drop
  2. Select your signed OSL PDF
  3. File must be PDF format

Step 3: Wait for processing​

Our AI analyzes the document to extract:

  • Landlord name and address
  • Tenant name(s) and contact info
  • Property address
  • Unit details

Tips for best results​

Document quality​

  • Use scanned PDFs (not photos)
  • Ensure text is readable
  • Higher resolution = better extraction

Handling issues​

If extraction misses data:

  1. Check if the PDF is text-based (not image-only)
  2. Try a cleaner scan
  3. Manually enter missing fields

Storing the original​

The uploaded PDF is stored and linked to the lease:

  1. Go to the lease detail page
  2. Find "Documents" section
  3. View or download the original OSL

Re-processing​

There's no standalone "reprocess without a new file" action — to re-extract, re-upload the document:

  1. Navigate to the lease's Overview tab, in the Documents area
  2. Click Replace Document and upload the file again
  3. Review the new extraction
  4. Update fields as needed
