For the first time since August, the Canadian dollar is worth less than a US dollar.
The 1:1 ratio is a psychological benchmark used by most people with respect to the dollar. This is actually arbitrary in light of the fact that the currency could be scaled 1:100 and be called the “Canadian Wazoo” which trades at 572 to 1 US dollar and then such comparisons would no longer be used. Both are equally invalid.
