Short answer
Not necessarily. An assignment can transfer contractual rights and obligations without fully releasing the original purchaser. If the assignee fails, the builder may still have rights against the assignor depending on the agreement, consent and release. Ask your lawyer for the answer in writing before treating the deal as finished.
The client problem behind the question
The assignor believes the risk ended when the assignment agreement was signed and the deposit was reimbursed. Near final closing, the assignee cannot obtain financing. The builder then looks back to the original contract and the parties named in it.
A practical Ontario example
Illustration only: The assignee’s mortgage is declined after a low appraisal. The builder’s consent acknowledged the assignment but did not contain a full release of the assignor. The assignor now needs urgent legal advice and may need to help complete, replace the assignee or negotiate while preserving claims between the parties.
Questions Rajiv would ask before suggesting a route
- Does the builder’s consent expressly release every original purchaser and guarantor?
- What indemnity does the assignee give the assignor?
- Who controls communication if financing fails?
- Can the assignment be replaced before closing?
- What remedies and losses could follow a default?
Practical routes to compare
- Require proof that the assignee has a credible financing and cash plan.
- Use separate lawyers and written default remedies.
- Retain documents and monitor the builder closing rather than assuming silence means completion.
- Seek immediate legal advice if the assignee signals trouble.
Keep the decisions separate
- Contract and liability: the builder agreement, assignment documents and written consent are for the real-estate lawyer to interpret.
- Marketing and price: a Realtor can assess comparable choices and work within builder restrictions.
- Mortgage: the lender decides acceptable value, income, credit, documents and funding structure. A regulator does not set that lender policy.
- Tax: an accountant or tax lawyer should confirm GST/HST, rebate and income-tax treatment from the actual facts.
Where A, alternative, MIC and private lending may fit
An A lender is normally the first route when income, credit, debt ratios, property and current value fit. Alternative lenders can take a broader view of income or property at a higher cost. A MIC is an institutional mortgage lender and may offer a six-to-twelve-month or longer term, interest-only or amortized payments, open or partially open features, and sometimes a maturity matched to the planned exit. A private lender may also bridge a closing. A short-term approval is useful only when the client can explain how it will be repaid through refinance, sale or other documented funds.
Verified fact and current limitation
Release and continuing liability are legal and contractual questions. Builder consent alone should not be described as a release unless the documents say so and the assignor’s lawyer confirms the effect.
Source checked 2026-09-03: read the primary source. Builder wording, lender policy, taxes, appraisal and market conditions must still be verified for the file.
Pressure-test the answer
The route can fail if consent is refused, marketing is restricted, the assignee cannot finance, the appraisal is low, payment timing is unclear, tax is larger than expected, documents expire or the assignor remains liable. Keep a closing fallback, calculate the worst cash requirement and involve the lawyer before a contractual deadline is missed.
