I know mattamy prided itself for closing on time.

Having said that, your house can be delayed another year due to strikes, weather etc... and as long as Mattamy gives you 60 days notice you cannot do anything!!

Major Delay (of more than 15 days)
Your builder must notify you in writing at least 65 days prior to the original closing date in your purchase agreement in order to delay your closing up to a maximum of 120 days. As part of this notification, the builder must also set a new closing date which will be referred to as the “extended” closing date.
Minor Delay (of 15 days or less)
Your builder must notify in writing at least 35 days prior to the original or extended closing date in your purchase agreement in order to delay your closing up to 15 days. The builder must also set a new closing date at that time. However, if there has already been a major delay, the combined delay cannot exceed 120 days.

If you do not terminate the agreement before day 130, the builder gets another 120 days and if they still don't complete the house, the agreement is automatically terminated and you get your deposit back (with interest).

Mattamy's delays can be to their benefit. The market in Milton is HOT right now, so they could be taking this opportunity to oversell knowing fully well they will have to shuffle schedules around later. Meanwhile, if they expect a future lull, they've secured the premium price today's market commands. With up to a 4 month delay without the buyer being able to back out of the deal, they have a pretty sweet racket going here.

It says that they can only delay you a maximun of 120 days (4 months). At which point, if they fail to complete the house, you have from day 121 to day 130 to terminate the agreement. If you do not terminate the agreement before day 130, the builder gets another 120 days and if they still don't complete the house, the agreement is automatically terminated and you get your deposit back (with interest).
