Ontario vs BC Probate on a $1M Estate With a Cottage and Investment Account in 2026: Fee Calculation, 18-Month Timeline, and Whether an Inter Vivos Trust Saves $14,500

The Estate We're Modelling: $400K Cottage + $600K Investment Account

A Mississauga resident dies in 2026 leaving a $1M estate to two adult children. The principal residence (a Toronto-area family home) passes outside this calculation — it's covered by the principal residence exemption and held jointly with a surviving spouse. The probate base is the remaining $1M:

• $400,000 cottage in Muskoka, purchased in 2005 for $150,000 (current FMV $400,000)
• $600,000 non-registered investment account (adjusted cost base $350,000)

Both assets pass through the will. No beneficiary designations apply (neither is an RRSP, TFSA, or insurance policy). The full $1M hits the probate base in whichever province the deceased was legally resident at death.

Ontario Probate: $14,250 on $1M

Ontario's Estate Administration Tax Act charges a flat rate above a $50,000 threshold. The math is straightforward:

Ontario's system is effectively a 1.5% tax on everything above $50K. On a $2M estate, the fee doubles to $29,250. On a $500K estate, it's $6,750. The rate is flat — there's no progressive relief for smaller estates beyond the $50K exemption.

BC Probate: $13,650 on $1M

BC's Probate Fee Act uses a tiered structure plus a separate court filing fee:

BC's top rate (1.4%) is slightly lower than Ontario's (1.5%), so the gap widens on larger estates. On $2M: Ontario charges $29,250 vs BC's $27,650. On $500K: Ontario charges $6,750 vs BC's $6,475 (plus $200 filing). For the full provincial breakdown, see our probate fees comparison guide.

The Capital Gains Layer: What the Estate Actually Owes CRA

Probate fees get the attention, but the deemed-disposition tax under section 70(5) of the Income Tax Act is the real cost driver. At death, the estate is treated as having sold all non-sheltered assets at fair market value. Here's the calculation on our $1M estate:

Applying the post-2024 tiered capital gains inclusion rate:

• First $250,000 of gains at 50% inclusion: $125,000 taxable
• Remaining $250,000 at 66.67% inclusion: $166,675 taxable
• Total taxable capital gain: $291,675

At Ontario's top combined marginal rate of 53.53%, the capital gains tax on this estate is approximately $156,100. Even at a blended effective rate (assuming the deceased had modest other income), the tax bill is $100,000+. The $14,250 probate fee is less than 10% of the total estate cost. This is the part most “inheritance tax in Canada” searches miss — the deemed-disposition mechanics under section 70(5) are where the real money goes.

The 18-Month Probate Timeline: What Executors Face in Each Province

Probate isn't a single event — it's a sequence that stretches 12–18 months in both Ontario and BC. The executor is personally on the hook throughout.

The Inter Vivos Trust Strategy: Removing the Cottage From Probate

The idea is simple: transfer the $400K cottage into a living trust during the owner's lifetime. Since trust assets don't pass through the will, they're excluded from the probate base. The probate fee drops to the remaining $600K of investments that still go through the will.

Probate savings with the trust

Ontario math on $600K: ($600,000 − $50,000) × $15/$1,000 = $8,250. BC math on $600K: $0 + $150 + ($550,000 × $14/$1,000 = $7,700) + $200 = $8,050.

The costs the probate savings have to beat

Break-even analysis: Ontario trust for a $400K cottage

Using the midpoint estimates: $4,000 setup + $1,250/year ongoing costs vs $6,000 Ontario probate savings.

The PRE Trap: How a Trust Can Cost $89,000 to Save $6,000

The principal residence exemption under section 40(2)(b) of the Income Tax Act allows one property per family unit per year to be designated as the principal residence, eliminating capital gains on that property. Some families designate the cottage (rather than the family home) as the principal residence for certain years to reduce the cottage's embedded gain.

The problem: a standard inter vivos trust cannot claim the PRE unless it qualifies as a spousal trust, alter ego trust (settlor must be 65+), or joint partner trust. If the cottage is transferred into a trust that doesn't meet these conditions, the PRE is permanently lost on the cottage — even if it would have been available had the property stayed in the individual's name.

On our Muskoka cottage with $250,000 of accrued gain, the capital gains tax if the PRE is lost:

• $250,000 gain at 50% inclusion: $125,000 taxable
• At Ontario's top combined rate of 53.53%: ~$66,900 in tax
• If the gain exceeded $250K (which it would if the cottage appreciates further): the 66.67% tier kicks in, pushing tax toward $89,000+

Spending $4,000 on a trust to save $6,000 of probate and then losing $67,000–$89,000 of PRE shelter is the single most expensive estate-planning mistake on recreational property. Have an estate lawyer confirm PRE eligibility before transferring any property into a trust. For the cottage-specific capital gains walkthrough, see our inherited cottage guide.

Spousal Rollover: The Lever That Defers Everything

If the deceased has a surviving spouse or common-law partner, section 70(6) of the Income Tax Act allows all assets to roll over at the original adjusted cost base — deferring both capital gains tax and RRSP/RRIF income inclusion until the surviving spouse's death. On our $1M estate, the spousal rollover would defer the entire $156,000+ capital gains bill.

Probate fees, however, are not deferred by the spousal rollover unless the assets bypass the will through joint ownership with right of survivorship or direct beneficiary designations. The $14,250 Ontario probate fee still applies to assets that flow through the will, even when the surviving spouse is the sole beneficiary.

This is why probate avoidance and tax deferral are separate strategies that need to be planned together, not in isolation.

How Other Provinces Compare: Alberta, Manitoba, Quebec

Ontario and BC are among the most expensive provinces for probate. For context:

The difference between cheapest and most expensive province on a $1M estate exceeds $16,000. Province of residence at death is one of the largest single levers in estate-cost planning — and almost nobody thinks about it until the will is being probated. That said, don't move provinces solely for probate savings. Family, healthcare, climate, and income tax rates all dominate the probate math on most estates.

Canada vs US vs UK: The International Context

Canada's system is fundamentally different from the US and UK. Beneficiaries in Canada receive assets tax-free — the tax falls on the deceased's final return, not on the heir.

The US exemption at US$15M means most American estates pay zero federal estate tax. Canada's deemed-disposition system catches estates at much lower values, but at lower effective rates for most families. The UK's £325,000 threshold (frozen until April 2031) means far more British estates are exposed to IHT than Canadian estates are to deemed-disposition tax.

General Estate Planning Strategies That Actually Reduce the Bill

Beyond inter vivos trusts, several strategies reduce both probate fees and deemed-disposition tax on an Ontario or BC estate:

• Beneficiary designations on registered accounts: Naming a beneficiary on your RRSP, RRIF, or TFSA bypasses probate on those assets. On $200K of RRSP with a named beneficiary in Ontario, that's $3,000 of probate saved. The income tax on the RRSP still hits the terminal return (unless rolling to a spouse), but the probate fee is avoided.
• Joint ownership with right of survivorship: Assets held as joint tenants pass directly to the surviving owner, bypassing probate. Common for the family home (which is why it's excluded from our $1M model). Less straightforward for cottages — adding an adult child to title triggers a deemed disposition on the transferred share and may have land transfer tax implications.
• Life insurance with a named beneficiary: Proceeds pass outside the estate, bypassing probate and providing immediate liquidity to cover the capital gains tax bill. On our estate, a $200K policy would cover the bulk of the $156,000 deemed-disposition tax without requiring a forced cottage sale.
• Secondary will (Ontario only): Ontario allows a secondary will for private company shares that don't require probate, avoiding the Estate Administration Tax on those assets. Not applicable to our cottage-and-investment scenario, but relevant for business owners.

Bottom Line: What This Estate Actually Costs in Each Province

The inter vivos trust saves $6,000 of Ontario probate or $5,600 of BC probate — roughly 3% of the total estate settlement cost. On a $400K cottage, the trust breaks even on setup costs alone in year 1–2, but ongoing annual costs mean the net break-even is 3–5 years. On a $1.2M cottage (like our Burlington scenario), the probate savings jump to $18,000 and the trust math works much better.

The decision lever: on this $1M estate, the trust is marginal. What actually matters is whether the estate has $150,000+ of liquid capital to pay the capital gains tax without being forced to sell the cottage under CRA's deadline. A $200K life insurance policy with the children named as beneficiaries — premium maybe $3,000–$5,000/year depending on age and health — solves the liquidity problem and bypasses probate entirely. That's almost always the better play than the trust on a $400K cottage.
