Establish the actual move-to-personal-use date

Record the lease expiry or termination, tenant move-out, vacancy, repairs, renovation, insurance change, utility transition, furniture move and date the owner or family actually began ordinarily inhabiting the property. The end of rent, physical move and tax change date may not be identical.

Preserve the lease, notices, inspection reports, photographs, invoices and occupancy evidence. Ask the tax professional which fact pattern and date control. Do not choose a date merely because it creates a preferred market value or filing result.

Understand the deemed-disposition starting point

CRA guidance generally treats a full change from income-producing use to a principal residence as a deemed disposition at fair market value and reacquisition at that value, unless an available election postpones the reporting. The change can create a tax question even though title does not transfer.

Place the review in the conversion-year filing workback. Waiting until the eventual sale can leave the owner without reliable historical value, CCA and occupancy records.

Obtain fair-market-value evidence at conversion

Document the Calgary property as it existed on the relevant date: condition, deferred work, improvements, tenancy, title, parking, suite, lot or unit position and current comparable evidence. A later renovation or rising market can make retrospective value work contentious.

Use a qualified appraiser when the risk, elapsed time or complexity warrants it. City assessment and a real estate opinion can be evidence inputs, but the tax reviewer should confirm what support is appropriate and whether land and building allocations are needed.

Reconstruct CCA before discussing an election

Collect every T776, CCA class schedule, workpaper, addition, disposition and use-change record. CRA guidance indicates that a subsection 45(3) election is not available in the same way where CCA was claimed on the property for a period after 1984. The exact history must be reviewed.

Do not assume that a small annual CCA claim is immaterial or that the current UCC statement tells the full story. Reconcile filed returns by owner and year, including any co-ownership or entity changes.

Review subsection 45(3) timing and scope

A qualifying subsection 45(3) election can postpone the deemed disposition until the property is actually sold. CRA guidance states that the election is generally due by the earlier of 90 days after CRA asks for it and the filing due date for the year of actual sale. This timing differs from the home-to-rental election process.

Ask the advisor what the election does, whether it is available, how the later sale is reported and how principal-residence years and other properties interact. Keep the signed election and proof of filing with the permanent property file.

Close the rental operation completely

Reconcile final rent, arrears, tenant deposit, utilities, management, repairs, legal costs, vacancy and capital work. Separate rental-period expenses from personal-period costs and record the last income-producing date. Retain the final T776 and all source records.

Tenant rights, notices and deposit accounting remain separate Alberta legal tasks. A tax conversion plan does not authorize possession or override the Residential Tenancies Act. Obtain the appropriate legal guidance before ending the tenancy.

Define the future principal-residence position

Actual personal occupancy is part of the principal-residence analysis, but future exemption is not automatic. Track Canadian-residency years, family-unit facts, other owned properties and which years may be designated. Preserve the exact move-in and later move-out dates.

If another home is sold or retained around the same time, model the designation question across both properties with the tax advisor. Do not let the emotional label of home replace the year-by-year analysis.

Separate conversion work from later improvements

Document the property's condition and value before major personal renovations. Keep contracts, invoices, permits, proof of payment, insurance recoveries and completion dates for later adjusted-cost-base review. Reconcile any work started during the rental period separately.

A renovation budget, mortgage advance or City permit value is not automatically a tax cost. The source records allow the qualified professional to decide current expense, capital addition and personal-use treatment later.

Coordinate refinance, insurance, title and occupancy

Tell the lender and insurer about the occupancy change as required. Confirm title and co-owner rights before one person moves in, especially after separation, inheritance or family transfer. Check condominium and municipal restrictions for the intended use and renovation.

These answers do not decide the tax election, but they can change the effective timeline, property value and ability to occupy. Keep each discipline's conclusion and scope visible on the same conversion workback.

Create the eventual sale file at move-in

Store the acquisition records, rental history, CCA, conversion value, election, personal-use dates, improvements and other-property chronology together. Set an annual review and an immediate review trigger for another move, rental period, title transfer or sale.

Give the qualified accountant and Alberta lawyer the complete chronology before filing or selling. Verify professional status and use secure document exchange. The decision board can organize missing facts, but it cannot determine the election or tax result.

Frequently asked questions

Does moving into the rental automatically make it my principal residence?

Personal occupancy is relevant, but Canadian residency, family-unit years, other properties and designation choices still require review.

Can a subsection 45(3) election postpone the deemed disposition?

It may in qualifying circumstances. Prior CCA and other facts can affect availability, so obtain advice.

When is the subsection 45(3) election due?

CRA guidance generally uses the earlier of 90 days after CRA requests it and the filing due date for the year the property is actually sold.

Do I need a value if I plan to keep the home?

Yes, a fair-market-value issue can arise at the change of use even without an immediate sale, subject to any valid election.
