How to File Documents in Multiple Ontario Courts Efficiently (2026 Guide)

Handling filings across more than one court is a reality for many Ontario law firms, paralegals, corporations, and financial institutions. Whether managing related proceedings, enforcement actions, family and civil overlaps, or province-wide portfolios, multi-court filing Ontario requires careful coordination, precise compliance, and operational efficiency. Each court has its own rules, portals, timelines, and formatting requirements, and mistakes can quickly lead to rejected filings or missed deadlines.

Select Serve and File Process Server Inc. supports multi-court filing Ontario for clients who need documents filed accurately and on time across the Superior Court of Justice, Family Court, Small Claims Court, Landlord and Tenant Board, and appellate courts. Our team combines procedural knowledge with hands-on courthouse experience, offering reliable, end-to-end filing support.

This guide explains how to approach multi-court filing Ontario efficiently, including planning strategies, court-specific requirements, e-filing systems, timelines, and common pitfalls.

Why Multi-Court Filing Ontario Is Complex

Ontario’s court system is not centralized under a single filing process. Multi-court filing Ontario becomes complex because:

  • Different courts use different filing portals
  • Deadlines and cut-off times vary
  • Formatting and page limits differ
  • Service requirements are not uniform
  • Some filings must occur before or after service
  • Not all documents are eligible for e-filing

Without a structured approach, errors compound quickly.

Ontario Courts Commonly Involved in Multi-Court Filing

A multi-court filing Ontario workflow often includes the following courts:

1. Superior Court of Justice (Civil)

  • Statements of Claim
  • Motion Records
  • Applications
  • Affidavits
  • Enforcement materials

2. Family Court

  • Applications (Form 8)
  • Case Conference Briefs
  • Motions to Change
  • Continuing Record updates

3. Small Claims Court

  • Plaintiff’s Claims
  • Defendant’s Claims
  • Motions
  • Garnishments

4. Landlord and Tenant Board (LTB)

  • L1, L2, T2, T5 applications
  • Certificates of Service

5. Court of Appeal / Divisional Court

  • Notices of Appeal
  • Appeal Records
  • Factums

Each court has unique procedural expectations that must be respected.

Planning a Multi-Court Filing Ontario Strategy

Efficiency starts with planning.

Step 1: Map All Required Filings

For multi-court filing Ontario, create a master checklist:

  • Which courts are involved
  • Which documents belong to each court
  • Required service methods
  • Filing deadlines
  • Page limits
  • Filing fees
  • Required affidavits

This prevents last-minute confusion.

Step 2: Sequence Service and Filing Correctly

In Ontario, many documents must be served before filing, while others must be filed before service.

Examples:

  • Civil Statements of Claim: serve first, then file
  • Family Court Applications: serve, then file with affidavit
  • Small Claims Plaintiff’s Claims: file, then serve
  • LTB applications: file first, then serve

A correct sequence is essential for multi-court filing Ontario success.

Step 3: Prepare Court-Specific Versions of Documents

Documents often need slight adjustments depending on the court.

Examples:

  • Different backsheets
  • Different cover pages
  • Different affidavits (Form 16B vs Form 6B vs Form 8A)
  • Different font or spacing rules
  • Different exhibit labeling

Using one “generic” document for all courts is a common mistake.

E-Filing Systems Used in Multi-Court Filing Ontario

Understanding Ontario’s filing platforms is critical.

1. Civil and Family E-Filing (Justice Services Online)

Used for:

  • Civil motions
  • Applications
  • Family Court filings

Key points:

  • PDF format required
  • Size limits apply
  • Naming conventions must be followed
  • Filing confirmations should be saved

2. Small Claims E-Filing

Used for:

  • Plaintiff’s Claims
  • Defendant’s Claims
  • Motions

Small Claims has its own forms and acceptance criteria.

3. Landlord and Tenant Board Portal

Used for:

  • LTB applications
  • Certificates of Service

Service and filing timelines are tightly linked.

4. In-Person Filing (Still Required in Some Cases)

Not all documents are eligible for e-filing.

In-person filing may be required for:

  • Certain urgent motions
  • Sealed documents
  • Large records exceeding size limits
  • Some enforcement materials

Select Serve and File completes both electronic and in-person filings as part of multi-court filing Ontario support.

Managing Deadlines Across Multiple Courts

Each court has different cut-off times.

Typical Cut-Off Times

  • Superior Court: 4:00 PM
  • Family Court: 4:00 PM
  • Small Claims: 4:00 PM
  • LTB: varies by application

A multi-court filing Ontario strategy must account for:

  • Time zone consistency
  • Same-day filing requirements
  • Rush filing when deadlines collide

Professionals often schedule filings in priority order.

Coordinating Affidavits Across Courts

Every court requires its own affidavit format.

Common affidavits include:

  • Form 16B (Civil)
  • Form 6B (Family)
  • Form 8A (Small Claims)
  • LTB Certificate of Service

For multi-court filing Ontario, affidavits must:

  • Match the service method
  • Reference the correct documents
  • Be commissioned correctly
  • Be filed with the correct court

Mixing affidavit types is a frequent cause of rejection.

1. Centralized File Management: All documents are tracked in a single system with court-specific tags.
