This exemption is more limited than most first time home buyers realize, its not enough that this is your first home in British Columbia, to qualify you must meet all of the following criteria:
1) Be a Canadian Citizen or Permanent Resident.
2) Must have resided in BC for the last 12 months, and at least 2 of the last 6 tax years.
3) Must never held title to property any where in the world
4) Must not have previously applied for the exemption.
Usually, #2 causes the most problems. For example, if you are a college student in Ontario and you are moving out to British Columbia to start your first job. Upon buying your first home you would not qualify for the FTHB exemption as you have not resided in British Columbia for a sufficient time.
