For nearly 4 years, a skilled carpenter in a mid-sized Ontario city operated a residential renovation business without giving much thought to its legal structure. Work came through referrals, payments arrived by cheque or e-transfer, and the business existed as an extension of the carpenter's own labour and reputation. No incorporation documents were filed, no partnership agreement was signed, and no formal business registration was completed beyond what municipal licensing required. The arrangement functioned well enough while jobs remained modest in scope and the carpenter worked alone.

The situation began to shift when a longtime friend, an electrician with a complementary client base, proposed that the 2 of them combine their operations. The electrician envisioned a single enterprise that could offer comprehensive renovation services, share equipment and workspace costs, and pursue larger contracts that neither could manage independently. The electrician had been operating under a similar informal arrangement and assumed that joining forces would be straightforward. Neither had retained legal counsel, and their initial conversations focused on the practical mechanics of splitting revenue rather than the legal implications of working together.

Around the same time, a homeowner whose kitchen renovation the carpenter had completed 18 months earlier contacted a lawyer about water damage allegedly caused by faulty workmanship. The letter that arrived demanded compensation for remediation costs, replacement of damaged flooring and cabinetry, and loss of use of the kitchen during repairs. The total claim exceeded $47,000. The carpenter carried general liability insurance with a $1 million limit, but the policy contained exclusions for completed operations that the carpenter had not fully understood when purchasing coverage.

The convergence of opportunity and exposure forced questions that had never seemed urgent. Proceeding with the proposed partnership would mean sharing not only profits but also potential liability for each other's work. Incorporating might create a barrier between personal assets and business obligations, but would require ongoing compliance costs and formalities. Continuing as a sole proprietor preserved simplicity but left the carpenter's home, savings, and other personal property directly exposed to any judgment arising from the disputed renovation or future claims.

The carpenter's spouse, a bookkeeper with clients who operated under various structures, urged consultation with a lawyer before making any commitment to the electrician. The electrician, eager to finalize arrangements before the spring construction season, pressed for a decision within 30 days. The carpenter needed to understand what each structural option would mean for the existing claim, for the proposed collaboration, and for the long-term trajectory of a business that had grown beyond its informal origins.
