T2091 Principal Residence Designation Case Studies
6 worked T2091 Principal Residence Designation case studies — the position a client typically comes to us with, what we do, and what it is worth. Each is an illustrative example built on the rules that apply to t2091 principal residence designation work, not a specific client's file.
Client: An employee with foreign investment accounts · Where: Winnipeg, Manitoba · Engagement: 6 weeks, fixed fee
Annual saving$70,000
ReorganisationTax-neutral
StructureMatches operations
The situation — An employee with foreign investment accounts, Winnipeg, Manitoba
The structure at an employee with foreign investment accounts in Winnipeg, Manitoba needed fixing. The file was carrying foreign accounts that had crossed the T1135 threshold two years earlier. Every option for fixing it ran through a reorganisation that had to be done without triggering tax.
What we did for An employee with foreign investment accounts, Winnipeg, Manitoba
We worked with the client's lawyer. Together, we reported the disposition and filed the principal residence designation for the year of sale, closing the late-designation exposure before the CRA raised it. We also prepared the elections, resolutions and valuations the structure needed to stand up.
The result — An employee with foreign investment accounts, Winnipeg, Manitoba
The structure now matches the business. Annual saving of $70,000, and the reorganisation itself was tax-neutral.
Case Study 2 · Scaling without breaking
Second-Province Expansion Handled, $47,000 Of Cash Released — Self-Employed Consultant, Regina
The situation — A self-employed consultant, Regina, Saskatchewan
Revenue at a self-employed consultant in Regina, Saskatchewan was up sharply and cash was tighter than ever. Underneath it sat medical expenses claimed on a calendar-year basis when a shifted window was worth far more.
What we did for A self-employed consultant, Regina, Saskatchewan
We filed the outstanding T1135 disclosures under the voluntary disclosure route before the CRA raised them. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing.
The result — A self-employed consultant, Regina, Saskatchewan
$47,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.
Case Study 3 · Cash and remittance control

Instalment basisCurrent year
ReviewedQuarterly
The situation — A physician in their first year of practice, Guelph, Ontario
A physician in their first year of practice in Guelph, Ontario was paying instalments calculated on a prior year. That year no longer reflected the business. Years of small donation receipts claimed one at a time instead of pooled onto a single return was tying up $155,000 of cash.
What we did for A physician in their first year of practice, Guelph, Ontario
We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, we carried the capital loss back against gains reported in the prior three years and generated a refund rather than a carry-forward balance.
The result — A physician in their first year of practice, Guelph, Ontario
$155,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
Case Study 4 · Backlog brought current
$54,000 Of Arbitrary Assessments Vacated After 7 Years — Commissioned Salesperson, Hamilton
The situation — A commissioned salesperson, Hamilton, Ontario
7 years of unfiled returns had turned into notional assessments at a commissioned salesperson in Hamilton, Ontario. Underneath lay RRSP room accumulated over eight years and never used in a high-income year. Collections had already started.
What we did for A commissioned salesperson, Hamilton, Ontario
We reset the medical expense claim window, transferred credits between spouses, and applied the tuition and disability amounts to the return that used them. We then filed every outstanding year in chronological order so the CRA could vacate the notional assessments cleanly.
The result — A commissioned salesperson, Hamilton, Ontario
All 7 years were accepted as filed. $54,000 of arbitrarily assessed tax was vacated, collections action stopped, and the account is current for the first time in 7 years.
Case Study 5 · Planning that cut the bill

First-year saving$33,500
RepeatsAnnually
Filing positionUnchanged in risk
The situation — A full-time student with tuition credits and part-time earnings, Kitchener, Ontario
A full-time student with tuition credits and part-time earnings in Kitchener, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly. It still left three years of returns filed without the slips that had been mailed to an old address on the table.
What we did for A full-time student with tuition credits and part-time earnings, Kitchener, Ontario
We modelled the current position against the alternatives before changing anything. Then we pulled the full slip history from the CRA record, refiled the affected years by adjustment request, and recovered the credits that had been missed.
The result — A full-time student with tuition credits and part-time earnings, Kitchener, Ontario
The change saved $33,500 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.
Case Study 6 · Records and systems rebuilt
29 Months Reconciled And $20,500 Of Input Tax Recovered — Multi-Source Retiree, Lethbridge
Client: A retiree drawing from three sources · Where: Lethbridge, Alberta · Engagement: 7 weeks, fixed fee
Months reconciled29
Input tax recovered$20,500
Close time7 days
The situation — A retiree drawing from three sources, Lethbridge, Alberta
Nothing reconciled at a retiree drawing from three sources in Lethbridge, Alberta. Every filing started with 29 months of cleanup. The file was carrying a home sale never reported on the basis that the gain was exempt anyway.
What we did for A retiree drawing from three sources, Lethbridge, Alberta
We rebuilt from source rather than correcting on top of the existing file. We recalculated the instalments on the current year’s expected income rather than the prior year’s, which stopped the instalment interest from growing. Then we set the routine that keeps it clean.
The result — A retiree drawing from three sources, Lethbridge, Alberta
29 months reconciled to the bank. The close now takes 7 days, and $20,500 of previously unclaimable input tax was recovered in the process.
