- Get legal advice: For significant matters, consult a lawyer before sending
- Timing counts: Notice periods often start from receipt, not mailing date
- Personal service sometimes required: Mail isn't always sufficient for legal notice
Types of Legal Correspondence
Different types of legal mail have different requirements. Understanding what you're sending helps you choose the right approach.
Demand Letters
A formal letter requesting action (usually payment or cessation of behaviour). Common uses:
- Requesting payment of a debt
- Demanding return of property
- Requesting action before legal proceedings
- Cease and desist requests
Demand letters typically don't have specific serving requirements—regular mail is usually sufficient, though tracked mail creates a better record.
Landlord-Tenant Notices
Forms like Ontario's N4 (non-payment of rent), N5 (termination for cause), or N12 (landlord's own use) have specific requirements:
- Must use correct official forms
- Must provide correct notice periods
- Service requirements vary by province
- Some situations require personal service, not just mail
Legal Proceedings Documents
- Statements of claim
- Notices of motion
- Court filings
These typically have strict service requirements. Mail alone is often insufficient—check with the court or a lawyer.
Contract Notices
Notices required under contracts:
- Termination notices
- Breach notifications
- Exercise of options
Check your contract—it may specify exactly how notices must be delivered.
Understanding Service Requirements
"Service" in legal terms means properly delivering a document to the intended recipient. Requirements vary by document type and jurisdiction.
Personal Service
Some documents must be handed directly to the person:
- Original court documents in many cases
- Certain eviction notices
- Some family law documents
Mail doesn't satisfy personal service requirements.
Service by Mail
Many documents can be served by mail, but often with conditions:
- Must be sent to the correct address
- May require tracked delivery (Registered Mail)
- Notice period may add extra days for mail delivery
- Recipient's refusal to accept may count as service
Substituted Service
When personal service isn't possible, courts may allow alternatives:
- Service on a family member
- Posting on the door
- Publication in newspapers
This usually requires court approval.
Ontario Landlord-Tenant Example
For Ontario Residential Tenancies Act forms:
- Hand delivery: Effective immediately
- Mail: Add 5 days to the notice period
- Posting on door: Counts as day after posting
Always check the specific rules for your province and situation.
Sending Demand Letters
A demand letter formally requests action before legal proceedings. It's often required or expected before going to court.
When to Send a Demand Letter
- Unpaid invoices or debts
- Breach of contract
- Return of property
- Resolution of disputes
- Before small claims court
What to Include
- Clear identification: Your name, the recipient's name, the matter involved
- Statement of facts: What happened, with dates and specifics
- The demand: Exactly what you want (payment amount, action required)
- Deadline: Reasonable time frame for response (usually 10-30 days)
- Consequences: What you'll do if they don't comply (legal action, etc.)
- Contact information: How they can reach you to resolve the matter
Tone
Keep it professional and factual. Avoid:
- Threats beyond legitimate legal action
- Emotional language
- Personal attacks
- Exaggeration
Mailing Method
For demand letters, Registered Mail is recommended:
- Proves you sent the letter and when
- Requires signature on delivery
- Creates evidence for potential court proceedings
Sending Landlord-Tenant Forms
Landlord-tenant relationships are governed by provincial law. Service requirements vary.
Ontario (Residential Tenancies Act)
Common forms and their service options:
- N4 (Non-payment of rent): Hand, mail (+5 days), under door, in mailbox
- N5 (Termination for cause): Same options as N4
- N12 (Landlord's own use): Same options
- N1 (Rent increase): Same options
When mailing, add 5 days to the notice period to account for delivery time.
British Columbia (Residential Tenancy Act)
- Mail: Deemed received 3 days after posting
- Personal delivery: Effective immediately
- Posting on door: Deemed received 3 days after
Alberta (Residential Tenancies Act)
- Personal service: Effective immediately
- Registered mail: Effective when signed for
- Regular mail: Effective 7 days after mailing
Best Practices
- Use official provincial forms—don't create your own
- Keep copies with proof of mailing
- Consider multiple delivery methods simultaneously
- Document everything
Choosing the Right Mail Type
For legal correspondence, the type of mail matters:
| Mail Type | Cost | Proof | Best For |
|---|---|---|---|
| Regular Mail | $1.15 | None | Informal correspondence only |
| Registered Mail | $12-15 | Mailing date + signature | Most legal notices |
| Xpresspost | $15-25 | Full tracking + signature | Time-sensitive documents |
| Priority | $25+ | Guaranteed + tracking | Urgent legal deadlines |
Why Registered Mail?
- Proof of mailing date: Receipt shows when you sent it
- Signature on delivery: Proves recipient received it
- Tracking: Know when it arrives
- Legal admissibility: Courts accept Registered Mail receipts as evidence
What If They Refuse Delivery?
If the recipient refuses to sign for Registered Mail, the refusal is typically documented and may be considered valid service. Check with your provincial rules or a lawyer.
Using PostPal for Legal Correspondence
PostPal can help with some legal correspondence, but has limitations.
Good for PostPal
- Initial demand letters: Where tracked delivery isn't critical
- Follow-up correspondence: After formal notices are sent
- Information requests: To lawyers, government agencies, etc.
- Cover letters: Accompanying documents sent via tracked mail
Not Ideal for PostPal
- Documents requiring tracked delivery: PostPal uses standard Canada Post (no tracking)
- Court filings: Often have specific filing requirements
- Notices with strict service requirements: Use Registered Mail at a post office
A Practical Approach
For important legal notices, consider sending via multiple methods:
- Registered Mail for legal proof (at post office)
- Regular mail as backup (PostPal or standard mail)
- Email if you have their address
This creates multiple records and increases the chance of actual receipt.
Documenting Your Mailings
For legal correspondence, documentation is crucial. Here's how to create a proper record:
Before Mailing
- Make copies of everything you're sending
- Date-stamp or note the date on your copies
- Take photos of the documents if relevant
- Keep the original or a copy for your files
During Mailing
- Get a receipt (Registered Mail, Xpresspost)
- Note the tracking number
- Save the receipt—don't throw it away
After Mailing
- Track delivery online
- Save delivery confirmation
- Note the date of signature/delivery
- Keep all records together in a file
Creating a Record
For each legal mailing, create a simple log:
Document: Demand Letter to [Name]
Date sent: March 28, 2026
Method: Registered Mail
Tracking #: RN123456789CA
Delivered: April 1, 2026 (signed by recipient)
Deadline given: April 15, 2026
Frequently Asked Questions
Do I need a lawyer to send a demand letter?
No, you can write and send demand letters yourself. However, for complex matters or significant amounts, legal advice is valuable. A lawyer's letter may also be taken more seriously.
What if the recipient doesn't respond to my demand letter?
Follow through on what you stated in the letter—usually filing a court claim. The demand letter becomes evidence that you attempted to resolve the matter first.
Can I email legal notices instead of mailing them?
Depends on the situation. Some contracts allow email notice. Court documents and statutory notices usually require physical delivery. When in doubt, use mail (and keep the email as a backup).
What's the difference between Registered Mail and Xpresspost?
Registered Mail provides proof of mailing date and signature on delivery. Xpresspost adds faster delivery and ongoing tracking. For legal purposes, Registered Mail is usually sufficient and cheaper.
Can a landlord email an eviction notice?
In most provinces, no. Landlord-tenant notices typically require physical delivery. Check your provincial rules.
What if I can't find the person's address?
You may need to hire a skip tracer or process server, or apply to the court for substituted service (like posting in a newspaper). Sending to a last known address may be acceptable in some situations.
How long should I give someone to respond to a demand letter?
Typically 10-30 days, depending on the complexity of the matter and what you're requesting. Too short seems unreasonable; too long delays resolution.
Send Legal Correspondence with Confidence
When sending legal notices, demand letters, or landlord forms:
- Understand the specific requirements for your type of notice
- Use Registered Mail when proof of delivery matters
