🏡 Understanding Change-in-Use Rules & Section 45 Elections (Ultimate Guide)
When a property in Canada changes its use — for example, from your principal residence to a rental property, or vice-versa — important tax rules kick in. These are called change-in-use rules, and they often trigger Section 45 Elections under the Income Tax Act. As a tax preparer, understanding these is essential to avoid surprise tax bills and to maximize your client’s tax benefits.
🔁 What Is a “Change in Use”?
A change in use happens when a taxpayer switches the purpose of a property:
| Situation | Example | Result |
|---|---|---|
| 🏡 ➡️ 🏘️ Personal residence becomes rental | Moving out & renting the home | May trigger a deemed disposition & capital gain |
| 🏘️ ➡️ 🏡 Rental becomes personal residence | Moving into a former rental | May trigger a deemed disposition & capital gain |
💡 Deemed disposition means the CRA treats the property as if it were sold at fair market value — even if it wasn’t actually sold.
⚖️ Why Does This Matter?
Without proper elections, a change in use can trigger:
✅ Immediate capital gains tax
✅ Loss of principal residence exemption (PRE) for future years
❌ CRA scrutiny if not handled correctly
To manage this, the Income Tax Act provides Section 45 elections that can defer tax and protect the PRE.
🧾 Section 45(2) Election — Principal Residence ➜ Rental Property
🎯 Purpose
Allows a homeowner turning their residence into a rental to avoid a deemed disposition when it starts producing income.
✅ Key Benefits
| Benefit | Explanation |
|---|---|
| No immediate capital gain | Taxes deferred until actual sale |
| Continue claiming PRE up to 4 years | Home remains principal residence for up to 4 years while rented |
| Can be extended indefinitely | If taxpayer doesn’t claim CCA (capital cost allowance)** |
📌 Note: Claiming CCA on the rental property means you cannot use this election.
✉️ How to File
There is no CRA form. A signed letter must be sent to CRA when filing the return for the year change-in-use occurs.
Deadline: By the earlier of
📅 When CRA requests election OR
📅 Filing due date (usually April 30)
🧠 When to Use Section 45(2)?
✅ Client moves but plans to return
✅ Wants to keep home as investment
✅ Real estate market appreciating
✅ Wants to maximize PRE years
⚠️ When NOT to Use It
| Situation | Why Avoid |
|---|---|
| Property value dropped | Lock in loss instead |
| Planning to claim CCA | Election becomes invalid |
| Rental will be long-term | PRE years are limited |
🏆 Pro-Tip for Tax Preparers
Always ask for FMV (fair market value) at date of conversion — critical for future capital gain calculations!
🏘️ Section 45(3) Election — Rental Property ➜ Principal Residence
🎯 Purpose
Avoids a deemed disposition when a rental becomes a personal residence.
✅ Benefits
| Benefit | Explanation |
|---|---|
| No immediate capital gain at conversion | Defer tax until you sell |
| Allows claiming PRE in future | When the property becomes principal residence |
✉️ Filing Method
Same as 45(2) — letter to CRA, not a form.
🧠 When to Use It
✅ Client moves into a rental property they previously rented out
✅ Want to avoid immediate tax hit
✅ Market gains occurred during rental period
📦 Special Notes 🔑
📌 CRA Can Ask Later!
Election letters must be available — always keep copies.
📌 Non-Resident Warning
45(2) only applies if taxpayer remains a Canadian resident.
📌 Partial-Use Change
If only part of the home is rented (e.g., basement), special rules apply — may not be a full change-in-use.
🧮 Simple Example
Example: Turning Home Into Rental (45(2))
| Without Election | With Election |
|---|---|
| Deemed sale → Capital gain now | No deemed sale → tax deferred |
| PRE stops immediately | PRE continues up to 4 years |
| Immediate reporting required | Reporting deferred until sale |
🧠 Memory Tips for Exam + Practice
| Tip | Why |
|---|---|
| “2” = to rental | Section 45(2) for converting to income property |
| “3” = to residence | Section 45(3) for converting to personal home |
| No CCA ❗ | Claim CCA = lose election |
| Send letter not form | CRA currently requires letter |
✅ Quick Checklist for Tax Preparers
| Step | Check |
|---|---|
| 📍 Determine fair market value at change-in-use | ✔️ |
| 🏠 Confirm residency status | ✔️ |
| 📝 Prepare Section 45 election letter | ✔️ |

🎉 Final Thoughts
Section 45 elections are powerful tax tools, but only when used correctly.
They help:
✨ Defer tax
✨ Preserve principal residence exemption
✨ Avoid surprise CRA reassessments
As a tax preparer, review every client’s property situation annually — real estate changes are common, and mistakes here are costly.
🏠 Principal Residence Converted to a Rental Property — Rules & Real Examples (Beginner-Friendly Guide)
Converting a home from your principal residence to a rental property is extremely common in Canada — whether someone moves for work, health reasons, or investment purposes. However, this change can trigger major tax implications under change-in-use rules and Section 45(2) election.
This guide breaks down everything a new tax preparer must know — simply and clearly. ✅
🔁 What Happens When a Principal Residence Becomes a Rental?
When a homeowner starts renting out their principal residence, the CRA treats this as a change in use.
Without any election:
- 🏡 Deemed sale at fair market value (FMV)
- 💰 Potential capital gain triggered immediately
- 📄 Must report on Schedule 3 & Form T2091
- 🛑 PRE (Principal Residence Exemption) stops moving forward
Even though the person still owns the house, CRA treats it as though it’s sold and immediately repurchased at FMV!
🧠 Section 45(2) Election — The Key Tax Saver!
The Section 45(2) election allows a homeowner to avoid a deemed disposition and continue claiming the principal residence exemption for up to 4 additional years after converting to a rental property.
📌 What the election does:
✅ No deemed disposition at conversion
✅ No capital gains tax triggered at that time
✅ Property continues to qualify as principal residence up to 4 extra years
✅ Can be filed late with permission (section 220(3.2))
✅ Can be rescinded later if beneficial
🔔 Important: Only available if the taxpayer does NOT claim CCA (Capital Cost Allowance) on the rental property after 1984.
📦 Quick Rule Box
| Rule | Explanation |
|---|---|
| 🏡 + 🏘 | Change in use creates deemed disposition |
| ↩️ Section 45(2) | Stops deemed sale & extends PRE |
| ⛔ No CCA allowed | If CCA claimed, election not permitted |
| 📅 Extra PRE Years | Maximum 4 extra tax years |
| 📝 Filing | Letter, no CRA form |
| ⌛ Late filing allowed | CRA should not deny if conditions met |
✋ Family Unit Reminder
⚠️ Only one principal residence per family unit per year
(Couple + minor children count as one unit)
This election does not allow splitting PRE between spouses.
🧾 Real Example: Why Section 45(2) Matters
🎭 Scenario
Andrew’s Story
| Details | Info |
|---|---|
| Purchase year | 2006 |
| Lived in home | 2006 – 2015 |
| Converted to rental | 2015 |
| No CCA claimed | ✅ |
| Sold property | 2019 |
| Reason for move | Illness; lived with sister |
❌ If No Election Filed
- Deemed sale in 2015
- PRE shields gains up to 2015
- Any increase 2016–2019 becomes taxable
If home value rose significantly (common in Canada!), Andrew pays tax on that gain.
✅ With Section 45(2) Election
- No deemed sale in 2015
- Deemed to still be principal residence
- PRE extended 2016–2019 (4 years)
- No capital gains tax at sale
Andrew saves tax on all appreciation until the home was sold.
💡 Bonus Benefit
If Andrew later moved back into the home, the election would still prevent a deemed disposition on re-occupancy.
🧠 Practical Situations Where This Helps
| Situation | Election Useful? | Why |
|---|---|---|
| Moved for illness | ✅ | Financial relief & keeps PRE |
| Temporary work relocation | ✅ | Keeps PRE if returning |
| Testing new city before selling | ✅ | Gives time + tax protection |
| Real estate investment strategy | ✅ | Defers tax while renting |
🧩 When Not to Use Section 45(2)
| Avoid election if… | Reason |
|---|---|
| Home value is dropping | Lock in loss instead |
| You want to claim CCA | Disqualifies election |
| Rental expected long-term | PRE extension limited |
| Client already using PRE for another home | PRE restriction |
📁 Filing the Election
✉️ A written letter must be sent to CRA.
Include:
- Taxpayer name & SIN
- Property address
- Statement electing under Section 45(2)
- Date change in use occurred
- Affirmation no CCA claimed
✅ Keep a copy for audit purposes!
🔍 Quick Decision Checklist for Tax Preparers
| Question | Yes/No |
|---|---|
| Is client moving out & renting home? | ✅ |
| Will they avoid claiming CCA? | ✅ Required |
| Will they likely sell within 4 years? | ✅ |
| Do they want PRE for those years? | ✅ |
| Are there emotional / temporary factors? | ✅ (illness, job trial, etc.) |
If most answers are ✅ → Section 45(2) likely beneficial
✨ Final Thoughts
Section 45(2) is one of the most powerful tools for Canadian homeowners who convert their residence to a rental.
It allows:
🏡 Continue PRE for up to 4 years
💸 Deferral of capital gains tax
🛡️ Protection from immediate tax hit
📃 Flexibility (late file + rescind option)
Mastering this rule is critical for tax preparers — and a major value-add for clients.
🏘️ Rental Property Converted to Principal Residence — Rules & Real Example (Section 45(3) Election Simplified)
When someone moves into a property that they previously rented out, the CRA considers this a change in use — from income-producing property ➜ personal use property (principal residence).
Without planning, this change can trigger a deemed disposition and create a tax bill before the property is ever sold. 😬
This section explains the Section 45(3) election, which helps defer tax and maximize the Principal Residence Exemption (PRE) — beginner-friendly, tax-preparer approved ✅
🔁 What Happens When a Rental Becomes a Principal Residence?
Default CRA rule (without election):
- 📅 At the moment the owner moves in
- CRA treats the property as deemed sold at fair market value
- 💰 Capital gain must be reported immediately
- ⏳ Deemed reacquired at FMV for future tax calculations
- 🧾 Must report on Schedule 3 & T2091 form
❗ This creates tax even though the property was not actually sold!
Many people may not have funds to pay that unexpected bill.
✅ The Solution: Section 45(3) Election
The Section 45(3) election allows taxpayers to avoid the deemed disposition when converting a rental property into a principal residence.
✨ Key Benefits
| Benefit | Why It Matters |
|---|---|
| ⛔ Avoid immediate capital gains tax | No tax bill when moving in |
| 🕒 Tax deferred until actual sale | Pay later, not when moving |
| 🏡 Continue claiming PRE | Shield significant capital gains |
| 🧮 Add up to 4 years to PRE calculation | Extra tax-free years even if not living there before |
📎 Conditions to Make the Election
✅ Property must actually become the taxpayer’s principal residence
✅ Must stop earning rental income
✅ No CCA (Capital Cost Allowance) claimed after 1984 by taxpayer/spouse/trust
⚠️ Claiming CCA on a rental property disqualifies this election — always check tax history first!
📦 Quick Reference Box
| Rule | Explanation |
|---|---|
| 🏚️ Rental ➜ Home | 45(3) applies |
| 🚫 CCA allowed? | No CCA taken |
| 📄 CRA form? | No form — letter required |
| ⏳ Extra PRE years | Up to 4 years before or after move-in |
| 💰 Purpose | Defers gain & increases shelter |
🤓 Why 45(3) Is So Valuable
This election allows owners to:
- Treat up to 4 years before moving in as “principal residence years”
- Add +1 bonus year via PRE formula
- Reduce taxable capital gain dramatically when they sell
📚 Real-Life Example — The Smith Family
| Event | Year |
|---|---|
| Bought property | 2003 |
| Rented property | 2003–2009 (6 years) |
| Moved in (PR now) | 2009 |
| Sold home | 2011 |
| CCA claimed? | ❌ No |
| Election filed | Yes, under 45(3) |
🧾 Scenario Comparison
❌ Without Section 45(3)
- Deemed disposition in 2009
- Pay capital gains tax on 2003–2009 increase
- No sale yet = hard cash drain
✅ With Section 45(3)
Smiths can claim:
| Years | PRE Treatment |
|---|---|
| 2009–2011 | Actual years lived in home (3) ✅ |
| 2005–2008 | Bonus years allowed under election (4) ✅ |
| Bonus year rule | +1 ✅ |
Total PRE years = 3 + 4 + 1 = 8 years
Total ownership = 9 years
🏁 Tax Result
8/9 of capital gain exempt ✅
Only 1/9 taxable 🎉
This is a powerful tax win — made possible by Section 45(3).
💡 Key Takeaways for New Tax Preparers
| Concept | Why It Matters |

Understanding this election = high-value service to Canadian homeowners 🏡🇨🇦
🎯 Budget Changes & Strategic Approach to Section 45 Elections (Beginner-Friendly)
When dealing with the Principal Residence Exemption (PRE) and change-in-use rules, it’s crucial to understand how Section 45(2) and 45(3) elections evolved — especially after the 2019 Federal Budget updates. These updates strengthened planning flexibility for taxpayers and increased CRA scrutiny.
This section breaks everything down in simple terms so you can confidently apply these rules as a tax preparer. 🌟
🏛️ Key Budget 2019 Changes That Affect Section 45 Elections
✅ 1. Removal of the 4-Year Limit for Employment Relocation
If a taxpayer converts their principal residence to a rental property because of job relocation, the 4-year limit for the Section 45(2) election no longer applies.
👤 What this means:
- If a client moves to work in another city and rents out their home…
- They may claim the property as their principal residence indefinitely (not just 4 years) as long as conditions are met ✅
- Saves potentially huge capital gains on a rising-value market property (ex: Toronto, Vancouver)
📌 Hot Tip Box
💡 Always ask whether the move was employment-related. It may unlock unlimited PRE years — a massive tax advantage.
✅ 2. Section 45 Elections Apply to Partial Changes in Use
Previously, 45(2) and 45(3) applied only when a property completely changed use.
🏡 Now they also apply when only part of the home changes use, for example:
| Situation | Election Applies? |
|---|---|
| Duplex where owner moves into 1 unit while other stays rented | ✅ Yes |
| Basement apartment added to home | ✅ Yes |
| Partial Airbnb conversion | ✅ Yes (depending on use and CCA rules) |
📌 Note Box
⚠️ This is big! Mixed-use and multi-unit properties benefit — but CRA now pays closer attention to partial PRE claims.
🔍 CRA Oversight Is Increasing
Since 2016, CRA requires PRE reporting. Pair that with the 2019 flexibility → CRA now actively reviews:
- Missed elections ✅
- Incorrect PRE claims ✅
- Improper rental/partial use reporting ✅
Tax preparers must be extra diligent.
🧠 Strategy: There Is No One-Size-Fits-All Answer
Section 45 elections are not automatic. They require judgement.
When deciding whether to elect:
| Consideration | Why It Matters |
|---|---|
| Property value growth | Higher growth = election more valuable |
| Length of rental/absence period | Impacts PRE eligibility |
| Future sale plans | Tax triggered later vs. now |
| Employment relocation? | Removes 4-yr limit |
| Expected market increase | Big gains ahead = election often better |
📘 Example Thought Process (Simplified)
👨💼 Client lived in home 30 years → converting to rental in 2020.
purchase: $200,000 → now worth $2,200,000
Potential future increase: +$2M in next 10 years
Two choices:
| Option | Result |
|---|---|
| Trigger gain now | PRE shields full $2M past gain; tax applies only to future growth |
| File 45(2) election | Defer gain; PRE covers past + up to 4 yrs (or unlimited if relocation) |
📊 If massive future growth expected, election makes sense.
🏁 If not — trigger now & lock in tax-free gain.
🚀 Best Practice Decision Checklist
Before choosing election:
✅ Confirm change-in-use type (full or partial)
✅ Ask: employment relocation?
✅ Estimate: past gain vs future expected gain
✅ Check if CCA has been claimed (affects eligibility)
✅ Model both tax outcomes
✅ Document client decision & reasoning
📂 Filing & Late Filing
📝 Elections are filed by letter — no CRA form.
👍 Can be filed late if conditions met (important for cleanup cases!)
📌 Pro Tip Box
📁 Keep proof the property was intended/used as a principal residence (bills, ID, occupancy records, moving docs).
🧵 Final Takeaways
| Key Point | Why It Matters |
|---|---|
| Budget 2019 enhanced flexibility | More years protected from capital gains |
| Partial use now eligible | Duplexes/basements no longer excluded |
| More CRA scrutiny | Get documentation right |
| Run numbers — every client is unique | No cookie-cutter approach |
🛠️ Summary for Your Toolkit
As a new tax preparer:
🌟 Always ask client long-term plans
🌟 Always consider future appreciation
🌟 Check relocation rules
