Lynn, do you have a support network of friends or family who may be able to provide room and board for a while? Your husband, to put it as politely as I can articulate, seems like a piece of trash. And I'm pretty damn sure that polygamy of any kind is illegal here in Canada. In your case, it amounts to emotional abuse at the very least; I'm sure the government or a large number of NGOs might be willing to help you, too. You're obviously no longer happy in that marriage, and unhappy with the fact he's taken another partner. His 'religious' union with another woman proves that he doesn't care for you as he should. You shouldn't have to feel trapped. And he has literally threatened your emotional well-being, saying that any attempt at a divorce would get 'ugly'. Start focusing on finding ways to facilitate a separation - The law would back you fully if you sued for financial child support, I'm sure. There are always options, don't give up. And if you feel you're ready, start looking for other potential partners. He's certainly no longer faithful. Your life is yours; take it back by any means necessary.

Regarding your daughters: There's little question that you would probably get full custody, even if he fought for it legally. The Canadian government would make sure you had the means to support them, one way or another. For a while, life would neither be comfortable nor without stress, but you'd be free.
