Rent increased!

Like the title says , our rent is increased from 2300 dollars to 2600 dollars . It’s a one bedroom room condo around 600sq feet,parking and locker not included. Its a new condo so I think it doesn’t come under rent control.Our landlord had sent a N2 notice on August 29 and wants the increase by Dec 1. We asked if the new rent increase could be slightly lowered to which the landlord straight up refused and said it’s on par with the current market . We cannot afford this increase. What are my legal options? Is there anything we can do help to ourselves in this situation?
