Ontario HST rebate: Do common-law couples qualify for the couples (family) rebate?

Question

Do common-law couples qualify for the couples rebate?

Answer 1

Yes. Refer to the Ontario Ministry of Revenue's FAQ titled Who qualifies as a family? Quote:

Who qualifies as a family?

Married couples or common-law partners (with or without children) and single parents will qualify as families. [emphasis mine]

Of course, you ought to have filed your income tax returns to reflect such status.
