There is no answer to this question, because no one knows how many soldiers have died in war (as you said "gone to war", I presume you mean soldiers rather than non-combatants). Even in modern wars soldiers go MIA (missing in action) and sometimes no one ever finds out what happened to them. This would apply even more so in ancient wars, wars between tribes, guerrilla wars against occupying forces or colonial powers, or wars that took place over very large areas, such as the American Civil War and the two world wars. Often it is not known how many people even took part in wars, let alone how many were killed in them.
Before the year 1867, the British provided defence for Canada. Canadian soldiers were involved in many of the large well known wars such World Wars I & II.
