This is a worked example, not a real estate. Every figure below is computed — the faraid shares from the Qur’anic fractions, the Ontario column from the Succession Law Reform Act — at net estates of $250,000, $400,000 and $750,000, after funeral expenses, debts and any bequest.
Under faraid
The four schools do not divide this estate the same way. Each grouping below is what that school actually gives, on the researched positions in our madhhab register.
Hanafi
| Heir | Share | $250,000 | $400,000 | $750,000 |
|---|---|---|---|---|
| Mother | 1/3 | $83,333 | $133,333 | $250,000 |
| Paternal grandfather | 2/3 | $166,667 | $266,667 | $500,000 |
Maliki, Shafi’i and Hanbali
| Heir | Share | $250,000 | $400,000 | $750,000 |
|---|---|---|---|---|
| Mother | 1/3 | $83,333 | $133,333 | $250,000 |
| Paternal grandfather | 4/9 | $111,111 | $177,778 | $333,333 |
| Full sister (1) | 2/9 | $55,556 | $88,889 | $166,667 |
A grandfather surviving alongside siblings is a recognised point of difference: Abu Hanifa excludes the siblings entirely, while the Maliki, Shafi'i and Hanbali schools have the grandfather share with them, taking no less than one third of the residue. This calculator applies Abu Hanifa's rule for every school, so on the Maliki, Shafi'i or Hanbali position the grandfather's figure above is too high and the siblings' too low. Take advice before relying on it.

Under Canadian law
What Ontario does with the same family where there is no valid will, computed from the statute at three estate sizes. The $350,000 preferential share is a cliff edge: below it the spouse takes everything and the children take nothing at all.
| Who | $250,000 | $400,000 | $750,000 |
|---|---|---|---|
| Surviving parent | $250,000 | $400,000 | $750,000 |
Succession Law Reform Act, s. 47 (3); the $350,000 preferential share is set by O. Reg. 54/95. Ontario only — every province differs, several substantially.
Where in Canada changes the answer
The same family, the same estate, in each of the thirteen jurisdictions. Provinces that reach the same result are grouped together. All figures are for an estate of $750,000.
| Province or territory | How the estate divides |
|---|---|
| Ontario, British Columbia, Alberta, Saskatchewan, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Labrador, Yukon, Northwest Territories, Nunavut | Surviving parent $750,000 |
| Quebec | Parents (privileged ascendants) $375,000; 1 sibling (privileged collaterals) $375,000 |
Each figure is computed from that jurisdiction’s own statute. Follow any province above for its sections, thresholds and the things the arithmetic leaves out.
What makes the difference
The siblings take $500,000 here and nothing under the province, which pays them only when there is no spouse, child or parent. And the school matters here: Hanafi and Maliki/Shafi’i/Hanbali do not divide this estate the same way, which is unusual — the four schools agree on the arithmetic almost everywhere.
How it changes with the numbers
The same family shape, with different numbers of each heir. These sit on one page rather than several because only the arithmetic changes — the rules being applied are the same.
| The family | Faraid shares | Ontario at $750,000 |
|---|---|---|
| My father died, leaving his mother, his paternal grandfather and one sister | Mother 1/3, Paternal grandfather 2/3 | Surviving parent $750,000 |
| My father died, leaving his mother, his paternal grandfather and two sisters | Mother 1/6, Paternal grandfather 5/6 | Surviving parent $750,000 |
Real estates involve debts, taxes, beneficiary designations and jointly held property that change the arithmetic substantially. Run your own family through the calculator, then confirm the result with a scholar and a lawyer.
What this means where you live
The arithmetic above is the same in every province. What changes at each border is whether the will carrying it is valid, and what happens to the estate if there is no will.
