How Do I Write a Contract That Actually Protects Me?

Before you start: is the other side a business or a consumer?

The rules that apply to your contract depend heavily on who is on the other side of it. A business-to-business supply agreement is governed mainly by what the parties write and by default commercial statutes like the Interest Act and the Sale of Goods Act. A contract with a consumer, someone buying personal development services, or a person signing at their door, brings in mandatory consumer protection rules that cannot be waived. Knowing which category your contract falls into before you draft it determines which of the steps below actually apply.

Step 1: Decide how the contract will be formed and signed

In both Ontario and Alberta, electronic signatures and click-through acceptance are valid ways to form a contract. Ontario’s Electronic Commerce Act, 2000 says an offer or acceptance can be expressed through “an act that is intended to result in electronic communication, such as… touching or clicking on an appropriate icon” (s 19(1)). Alberta’s Electronic Transactions Act uses nearly identical wording (s 27). This means a signed PDF, a clicked checkbox, or an emailed acceptance can all be enforceable, so the contract should say clearly what action counts as acceptance.

There is one notable exception in Ontario: powers of attorney over an individual’s financial affairs or personal care cannot be validly executed under the electronic commerce rules (Electronic Commerce Act, 2000, s 31(1), para 3). If your contract includes a clause appointing someone to act on your behalf for financial or personal-care decisions, that portion needs to be handled on paper in Ontario.

Step 2: Write the payment and interest terms precisely

If a contract calls for interest but doesn’t fix a rate, federal law steps in: the Interest Act imposes a default rate of 5% per year (RSC 1985, c I-15, s 3). This applies across Canada, so silence on rate does not mean interest-free, it means 5%.

A more common drafting trap involves stating a rate as a daily, weekly, or monthly percentage. Under section 4(1) of the Interest Act, a clause like that is unenforceable above 5% unless the contract also states the equivalent yearly rate. A “2% per month” clause that never converts that figure to an annual equivalent risks being capped at 5% per year regardless of what was intended.

Step 3: Decide what happens to implied terms about goods

If the contract involves selling goods “by description,” both Ontario’s Sale of Goods Act (RSO 1990, c S.1, s 15, para 2) and Alberta’s Sale of Goods Act (RSA 2000, c S-2, s 16(4)) automatically imply a condition that the goods will be of merchantable quality, even if the contract never mentions quality at all.

This implied condition is not fixed. Both statutes allow it to be excluded or varied by express agreement (Ontario, s 53; Alberta, s 54). A contract that says nothing on the subject leaves the implied condition in place by default. A contract that wants a different quality standard, or wants to disclaim the implied condition entirely (for example, on used or as-is goods), needs to say so explicitly rather than staying silent.

Step 4: Decide whether to vary the limitation period

Both provinces set a basic discovery-based limitation period, the deadline for starting a lawsuit, of two years. Ontario’s Limitations Act, 2002 sets a basic two-year period along with a 15-year ultimate limit. Alberta’s Limitations Act sets the same two-year period, running from when the claimant knew or ought to have known the injury occurred (RSA 2000, c L-12, s 3(1)(a)).

In Ontario, a business-to-business agreement made on or after October 19, 2006 can vary or exclude this default limitation period by contract (Limitations Act, 2002, s 22(5), para 1). That means two commercial parties can, for example, agree to a shorter or longer window for bringing a claim than the statutory default. Whether the same flexibility exists in Alberta was not confirmed in the material available for this article, so an Alberta contract relying on a varied limitation period should be checked against Alberta’s own Limitations Act directly.

Step 5: Check whether consumer protection rules add mandatory content

If the other party is a consumer rather than a business, extra statutory requirements can apply in Ontario regardless of what the contract itself says:

• A personal development services agreement (gym memberships, coaching, and similar ongoing services) must be in writing and delivered to the consumer (Consumer Protection Act, 2002, s 30(1)).
• A future-performance consumer agreement, one involving ongoing or deferred delivery, must be followed up with a written copy within 30 calendar days of being billed, or 60 calendar days after the agreement is entered into, whichever applies (Consumer Protection Act, 2002, Part IV, as summarized by the Ontario government’s business guide).
• A direct agreement, most often a door-to-door sale, must include a 10-day cancellation right that lets the consumer cancel for any reason (O Reg 8/18).

Alberta has a parallel direct-sales rule: a direct-sales contract must give the consumer a 10-day, no-reason cancellation right stated in the contract itself (Direct Sales Cancellation and Exemption Regulation, Alta Reg 191/1999). The 10-day period is the same in both provinces, though it sits in different regulations.

Contracts that never touch a consumer, and don’t involve future performance, personal development services, or door-to-door sales, don’t need these clauses at all. Applying consumer-agreement wording to a pure B2B contract is unnecessary; missing it on a genuine consumer contract can undermine the whole document’s enforceability on that point.
