How much would the tax be on this LV clutch?

I want to get the Louis Vuitton Mini Pochette Delightful Monogram, and I'm in Canada. I was looking at youtube videos to see how much the tax was because I heard it was a lot. People in America were saying it was about like around $50. And then I came across another video and a person said she was from Canada saying it was a couple $ 100 and I'm like WHAT THE !@#$%^&*? So I'm wondering. Even if you're from the United States please tell me the item you got, price and tax. Oh and if you could calculate the tax for me on this, the price is $315. PLEASE HELP! Oh and btw I' not spoiled or anything, my birthday is coming up and I'm getting $100-200 from my grandma, and $50 from the rest of my family members because all i want is monaaaaaaaay. Haha lol
