This is wrong, (Edit: This language was too harsh, apologies)
ITAR is an American EXPORT restriction, not a Canadian IMPORT restriction. THe US border guards going in are not checking for ITAR as your are IMPORTING goods into the US, on the way out, the Canadian border guards;
a) don't know what ITAR is; and
b) don't care.
I've personally imported ITAR items across the border in person many times when I lived in Ontario, and there was never a problem.
