Don't bother - irrelevant - not the OP question. This information bulletin refers to gifts and their tax deductibility as in giving to a registered charity etc and what you can deduct.
Sorry, you are right. The tax Guide for Individuals states as follows;
Amounts that are not taxed
You do not have to report certain amounts as income,
including the following:
■ any GST/HST credit or CCTB payments, including those
from certain related provincial or territorial programs;
■ child assistance payments and the supplement for
handicapped children paid by the province of Quebec;
■ compensation received from a province or territory if
you were a victim of a criminal act or a motor vehicle
accident;
■ lottery winnings;
■
most gifts and inheritances;
■ amounts paid by Canada or an ally (if the amount is not
taxable in that country) for disability or death due to war
service;
■ most amounts received from a life insurance policy
following someone’s death;
■ most payments of the type commonly referred to as
strike pay you received from your union, even if you
perform picketing duties as a requirement of
membership; and
Note
Income earned on any of the above amounts (such as
interest you earn when you invest lottery winnings) is
taxable.
I guess it can depend on the type of gift and other circumstances if tax is payable.
