I just wrote the most recent offering of core 1 and tax was only mcq (but could definitely be asked in the case). From what I remember these are some of the questions:

When are taxes due if one spouse owns their own business (Sole proprietorship)?

When is rights and things due (when someone passes away)?

When is the final return due when someone passes away?

CCA question (calculation)

SBD question (calculation)

If a person moves to Canada from the USA for a new job and cuts all ties to the USA and signs a 1-year lease on a condo, what is their status for tax purposes?

These were exact questions asked, but obviously can vary...hopefully this gives you an idea of what to expect and to also let you know that 95% of people will NOT know the answer so some basic knowledge should be okay.
