This is a common issue. If you can specify shipping type from China (like DHL etc) then you will get it very quickly, and with a tracking number you can follow the entire way. When the draw is free shipping and a cheaper product, it may not be worth it to pay extra for better shipping.
I recommend purchasing from within Canada (see image). If you buy in sets of 5 or more, the cost of shipping you are paying within Canada is negligible, and you will get better pricing per item when you buy in bulk lots. And, for individual items, it may be worth it to pay a little bit more to insure that you get the product. The better price may not be worth it if you do not receive the product. For example, I have lots of 4 and 5 items with prices that can almost rival internationally sourced products (ie. approx. $1.60 to $3.00 each in lots of 4 and 5 with free shipping). This way you don't have to open disputes to get your money back. I imagine some Canadian sellers have shipping discounts when you purchase more than one item from the same store if you want different items.
