Personal Finances- divorce

I am pretty convinced sooner or later my marriage is over. I am trying to be as prepared as possible. I work and make decent money, we own a house which we bought 3.5 years ago. I paid the mortgage and all fixed bills for first 3 years, as my husband owns business and income is volatile. He also reports less income for tax purposes. Also I am primary (and sole) care taker of our toddler and house duties. Last year after getting fed up with his lack of support I put my foot down and stopped paying mortgage but continue to pay other expenses like hydro, electricity, starta, groceries and daycare etc. He is paying it now. As a result I ended up saving some money in my personal account. I want to know from your experience that will my husband be entitled to my personal savings in case of separation or divorce? We are in Canada, BC I am really overwhelmed right now but I need to cover my basis before anything happens.
