You can travel to the US as can any other Canadian.
The latest version of the travel ban, a proclamation of September 24, 2017, explicitly does not apply to
(iv) any dual national of a country designated under section 2 of this proclamation when the individual is traveling on a passport issued by a non-designated country;
(Section 3(b)(iv))
A similar exception exists in executive order 13780, of March 7, 2017.
See also CBP's FAQ concerning the executive order, before the proclamation was issued:
What about dual citizens?
Travelers will be processed according to the travel document they present. For example, if the traveler presents a Canadian passport, the Canadian passport will be used to process that traveler for entry.
The similar FAQ relating to the proclamation also quotes the proclamation's section 3 in answering the question "Who does the new Proclamation apply to?"
