I think there was something missed. The specific "tools" that Freeland is referencing ARE the powers to freeze those bank accounts. That IS the major tool that the government did not have.
I understand why Freeland would not want to outright say "we want the permanent power to freeze funds with no recourse" - but that's the only conclusion I could reach based on that clip.
Keep in mind, the government had the power to seize/freeze assets, before this Emergency Act, as long as they had a court order. However, that low bar seemed to be too high a hurdle so the Liberals want to make this permanent.
