Try, of all places, Walmart. They have a bunch at my local store in Ottawa, ON. I believe they were between $6 and $10 depending on size.
Another source is your dollar store but they tend to be on the smaller side.

I never buy vases from a regluar store anymore. I have found these type vases time and again at goodwill and other stores like that.
Also I work for a caterier. We have A TON of them. Florists leave the flowers in them and neither the bride or the florist want them back. I would check with where you are doing your wedding, or with your catier. They could have some that you could use.

Also I just was at goodwill this week, looking for books. And they had a few of these type vases for sale. they were $2.00 or less each. I am sure you could check somewhere like that by you. They may be different sizes but I’m sure you could find enough square ones…
