You can place flags where ever you wish. My main concern is the amount of red you are considering. The Canadian flag as you know is red and white. If you get white ink it will turn beige when tanned. Red will also fade, especially from exposure to sun. I've got tattoos where the red has completely disappeared in five years. Consider in perhaps ten years the only thing that would end up standing out would be the blue background of Old Glory. To make it last then I would suggest on your chest as it would not see the sun as much. Let me be the first to say, if this is your 1st of many, "Welcome to the club".
