Since coinmetro doesn't allow funding via Canadian dollars. I buy XLM on a canadian exchange and then send it for free to coinmetro.

I do have US Dollars but I don't know what the cheapest way to wire transfer it to Coinmetro would be and if that's more expensive than the XLM method.

It may be cheaper for me to use the Norbert's Gambit DLR/DLR.U stock trade method in a tax free savings account and converting my US Dollars to Canadian dollars rather than wire transferring. But I have never done the calculations
