Standard Life health insurance - BC canada

Anna
Does anyone else have standar life health insurance? It's through my spouses work, as extended medical but I also have regular government medical through my care card because I don't make enough money. I'm finding out so much, like my sons fillings were covered when they almost cost me 1500$ because he needed to be knocked out cuz he was 4 when they were done (no fluoride in our water, didn't know) but my question is how do I go about finding out if they will cover a breast pump for me? I've seen so many people posting about health insurance and breast pumps that it would be wonderful to see if I could get that a well.
