You will calculate the value of each of your assets accumulated during the marriage. This includes the value of TVs, cameras, computers, but it will not be the amount paid, it will be their current resale value. Generally if you look for similar items on Craigslist and total the value, this will be acceptable, but make sure to copy the ads so you factually show that you made a clear effort to obtain the fair value.
If the items "yours" then you keep them, but the dollar value goes into your side of the ledger. Things like TVs and furnishinings, you may want to split them, you take the TV, she takes the dining table. Or one person can take them but during equalization you account for the value.
So in this way, the value of items is accounted for, if there is credit card debt that paid for them, this is accounted for separately.
Debt that is held jointly, in both of your names on record with the bank, should be split equally.
Debt that is held in her name is hers, debt that is in your name is yours, regardless of what was purchased. This isn't always "fair". If I pay thousands of dollars for a vacation, I will be stuck with the debt. However consider what would happen if I paid cash for that vacation 5 years ago? Am I going to somehow convince the courts that I should be reimbursed? This is exactly why the debt in your name is yours, it is no different than if you spent cash on your ex or your family.
There are two basic scenarios that can play out. Ontario Family Law does not allow someone to show a net value below $0. This means that if there are few, or no assets (this is common in a short marriage when you are fairly young, rental home or apartment and no investments) then you both just show a Net of $0, you do not split the debt. This is how the courts would see it. If you go to mediation, you may come to a different agreement.
If you took out a loan for your partner's education or something else that was clearly for their benefit alone, you can try to make an argument that you should be reimbursed. This type of argument has little to do with family law and can just as easily (or more easily) be settled in small claims court. It won't fall under the Family Law Act or the equalization method. In Family Court you would approach this with an unjust enrichment claim. Don't bother if it is a few thousand dollars, it will cost you ten times that much in legal fees.
The other scenario that plays out is if there are sufficient family assets. RRSPs, house, cars, etc. There is more than enough on each side of the ledger and you don't have a net debt. This is the more common situation for established families. In this case, the debt is subtracted from your assets, so you each show a net asset. Then there is an equalization so each walks away with the same amount. From the situation you describe, you don't fit this scenario.
