A buyer submits an offer with a financing condition that expires at 11:59 PM on March 15th. The buyer's mortgage application is denied on March 14th, but they don't notify the seller until March 17th. What is the legal status of this condition?

Option B: The buyer can still remove the condition since they were denied financing before the deadline

This is incorrect because the timing of the mortgage denial is irrelevant if proper notification wasn't given before the deadline. While the buyer was denied financing before March 15th, they failed to communicate this to the seller within the required timeframe. Contract law requires both the occurrence of the triggering event AND timely notification to properly invoke a condition.

Option C: The seller can choose whether to accept the late notification or declare the condition waived

This is wrong because sellers don't have discretion to accept or reject late notifications regarding conditions. Once a deadline passes without proper action by the benefiting party, the condition is automatically waived by operation of law. The seller cannot choose to reinstate an expired condition, as this would undermine the certainty that deadlines are meant to provide in contractual relationships.

Option D: The condition remains valid until the buyer provides written notification regardless of timing

This is incorrect because it ignores the fundamental principle that conditions must be acted upon within their specified timeframes. Canadian contract law doesn't allow conditions to remain indefinitely valid simply because written notification was eventually provided. The deadline creates a firm cutoff point, after which the condition is automatically waived regardless of subsequent communications or circumstances.
