Ontario's Succession Law Reform Act, R.S.O. 1990, c. S.26:
The practical sequence: decide the executor and guardian → list assets → draft → sign in one sitting with two independent adult witnesses who are not beneficiaries, all three in the room, everyone initialling any page that isn't the signature page → store the original.
On validity: yes, if executed correctly. Ontario has no notarization requirement and no mandatory lawyer. A properly signed and witnessed Willful or LegalWills document is a valid will, and a holograph will written by hand is valid too.
The difference is what is in it, and what happens after death: - Courts have flagged the gap directly: with a holograph or DIY document there are no lawyer's notes, no reading-over, no supervised execution, and no witnesses who can later testify about capacity (McGrath v. Joy, 2020 ONSC 7454, para 35). Those records are what defeat a challenge. - A bad clause is worse than no clause. The classic online-service failure for his exact situation is a single will that names the private corporation's shares in the estate — see the next section, which is the most expensive mistake available here.
Ontario Estate Administration Tax is $15 per $1,000 (1.5%) of estate value above $50,000. Shares of a private corporation held in a single will are counted in full.
| Value of probate assets | EAT with one will |
|---|---|
| $150,000 | $1,500 |
| $300,000 | $3,750 |
| $600,000 | $8,250 |
| $900,000 | $12,750 |
A primary will + secondary will structure keeps the corporation's shares in the secondary will, which is not probated — so they never enter that calculation. GTA lawyers quote $500-$1,500 extra for the second will. The break-even is a share value of roughly $150,000: above that, the secondary will pays for itself immediately, and at $900,000 of holdco shares it saves $12,750 of EAT against roughly $1,500 of fees.
None of LegalWills, Willful, Epilogue or LawDepot offers a secondary will. That, not the price, is the reason an online will is the wrong instrument for someone who owns a professional corporation.
| Provider | Will only | Will + both POAs, one person | Couple, wills + all POAs |

| LegalWills.ca (online) | $49.95 | $99.95 (Premium package) | $79.95 two wills / $149.95 two Premium |
| Willful (online) | $129 | $199 | $349 |

| Oathstone Law (Markham) | $500 + HST | $700 + HST | $1,200 + HST |
| Barbarian Law | $750 + HST | $1,000 + HST | $1,600 + HST |
| Wannes Law (Toronto) | $750 + HST | $1,000 + HST | $1,750 + HST |
| Angrove Law | $795-$1,295 | $995-$1,495 | $1,595-$2,295 |
Industry benchmark (eState Planner's Estate Practice Report): the average spousal estate plan is $1,450 nationally and $1,750 in Toronto/GTA; 91% of estate lawyers now charge flat fees.
A lawyer-drafted couples plan with a primary and secondary will — roughly $1,600-$1,750 + HST in the GTA. The gap between that and a $149.95 online plan is about $1,450-$2,145. If the clinic shares are worth more than ~$150,000, the secondary will alone returns that on day one through saved EAT, before counting the guardianship and trust clauses for two children under 7.
If he wants a stopgap this week instead: a LegalWills couples will at $79.95 executed properly is a valid will and is far better than nothing — but it will need to be redone once the corporation shares go in, and that is a second set of fees.
