I tend to agree... Cnaada doesn't really have any history nor does it still have any identity on its own since it had only become a country since 1867. What is now considered Canada, their foreign relations were handled by Britain prior to 1867 and even up to 1931 and 1982 respectively, the British still retained a great deal of legislative control from Westminster. 

 I think that it should be considered that any history before 1867 should be delated from this article since it is already covered in United Kingdom-United States relations. Canada had no relations with the US because Canada did not exist prior to 1867.
