Here's what the contract says:
This offer is conditional upon the Buyer obtaining an existing status Certificate from the seller at Seller's expense within Tenbanking days from acceptance of this offer and this offer is conditional upon the buyer finding the aforesaid certificate to his/her satisfaction, in his/her sole discretion, within Three banking days after receiving same, otherwise this offer shall become null and void and the deposit shall be returned to the Buyer without interest or deduction. This condition is included for the benefit of the Buyer and may be waived at his sole option.
Upon Status Certificate was reviewed by my lawyer, he suggested to add a few other clauses to protect me (the buyer) from some unexpected circumstances. The seller would normally have no reason to reject them provided that everything is fine with the unit. If the seller does not agree those additional clauses, what leverages do I have? Can I threaten to void the contract using the above condition? Note that my lawyer didn't find anything that is absolutely unacceptable in the status Certificate. The only findings that I can be unsatisfied are subjective ones, such as pet policy, parking spot size, etc. I live in Ontario, Canada.
