The relevant provisions of the Income Tax Act as amended by Bill C-208 would apply to a transaction undertaken today. That's based on yesterday's press release. The government announced that any new amendments would not apply before November 2021. For any transaction undertaken between now and the end of October, the government announced that whatever new conditions it might include in the bill, which, again, would need to be passed by Parliament, would not apply.
On July 20th, 2021. See this statement in context.
