You can sue for your actual out-of pocket expenses plus lost profit on the job, i.e. what you would have made in profit if you had completed the contract and been paid timely.
I'm sorry to hear about the situation you're facing with the customer cancelling the job unexpectedly and causing financial and personal stress. It's important to protect your business and seek compensation for any damages caused. In situations like this, it may be helpful to seek legal advice. I was lucky enough to deal with a responsible waterproofing company https://stellarwork.ca/ . They took the time to thoroughly explain the process and answer any questions I had.
