Short answer
An assignment clause is permission to ask for a transfer, not a guaranteed exit. Before signing, have a real-estate lawyer confirm whether assignment is allowed, when it can happen, whether the builder can refuse consent, what it costs, how it may be advertised and whether you remain liable after the transfer.
The client problem behind the question
The sales conversation may sound like, ‘You can always assign it later.’ Years later, the buyer discovers that marketing is restricted, consent is discretionary, the fee has increased or the builder will not release the original purchaser.
A practical Ontario example
Illustration only: A buyer signs at $780,000 expecting to move in. Two years later the buyer relocates for work. The agreement permits one assignment only after the builder reaches a stated construction milestone, prohibits public advertising and requires written consent plus legal and administration charges. The clause helps, but it does not create an immediate or cost-free sale.
Questions Rajiv would ask before suggesting a route
- Is assignment permitted, prohibited or subject to the builder’s discretion?
- When can I request consent and can the builder delay it?
- Are MLS, social-media or other public advertisements prohibited?
- What fees, legal costs, HST or profit-payment rules apply?
- Does consent release me if the assignee fails to close?
Practical routes to compare
- Negotiate a usable assignment provision during the cooling-off review if the builder agrees.
- Proceed only if you can still close without relying on assignment.
- If circumstances later change, compare assignment, closing, renting and a negotiated builder solution before a deadline.
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
Tarion says a pre-construction purchase agreement is a binding contract and recommends review by a lawyer experienced in pre-construction transactions. The assignment rights themselves come from the signed agreement and any builder consent, not from a general right to resell.

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.
