It's good that the order has been made. If it hadn't yet, you would likely be out of time to take it to court due to limitation periods. But orders don't expire once made, so if when you get the order that's the first step. Look at it closely, make sure you know what it says, and calculate the amount now due given the passage of time and the interest rate specified in the order.
If you go to court for the order, take it to the Registrar's or Sheriff's desk to ask about enforcement measures. Enforcing the order is a separate matter.
There are several options for enforcement, and the more you know about the defendant the better, including:
Full Legal Name
Social Insurance Number
Real estate or other property they own
Which bank they use, and which branch
The more you know the better. You should be able to find out a surprising amount by internet searching. People put a lot of information on social media, and even if they don't their friends and co-workers often do. Search the name and other information you know currently, including last known address. By following links and using image searching you'll get a lot. If you're not intuitively good at this, get someone who is net savvy to do it for you. It's public information. If necessary, get a lawyers office to do a PPSA search for property owned, a request to the Ministry of Transportation for current driver's license address, and other small such tricks to get info. That shouldn't cost much and will be valuable.
When you know as much as you can without hiring a private investigator, go back to the court and fill out the forms for enforcement. Depending on how much you know about her, you can get a writ for search and seizure of property, a lien on vehicles or real estate owned, garnish bank accounts or employment earnings, and subpoena them for an examination under oath about their assets and finances.
This could take some time and effort, but unless she has left the country and has no assets, or claims bankruptcy, you'll get your money eventually. If she's already gone bankrupt then it doesn't apply to you unless you were served those documents informing you of such.
