I have finally received my interview call and it is in Detroit.I have also got my three month Us visa of B1/B2 type.IT is written on the annotation on the visa 'travel to disney'.

Can I with this visa travel to Detroit and enter the US for the canadian interview?

will be indeed grateful for an answer.

In addition, our law firm can never advise anyone to violate the specific terms indicated upon visas.

In this case it would appear that the US visa may contain a specific restriction, indicating that the visit-entry is for a single specific purpose (ie: visiting Disney). But again, we would advise confirming the restriction with US authorities, or a US advisor/lawyer to be certain.
