Filing for an uncontested divorce in Ontario involves a few steps:  

1. Prepare the required documents: Fill out Form 8A (Application for Divorce) and gather your original marriage certificate.

2. File the application: Submit your completed form and pay the filing fee at the court or online.

3. Serve your spouse: Deliver the documents to your spouse, either by someone 18 or older or through a professional service.

4. Wait for a response: If your spouse doesn’t respond within 30 days (in Canada), you can proceed.

5. Finalize the divorce: After filing more paperwork and paying additional fees, the court will issue the divorce order.
