Yes. The interim report that has to be filed will cover the pre-writ period or whatever period of time during the election campaign itself in which a party starts spending and crosses the threshold of $10,000, so there will be a disclosure if anyone participates.
Some people have said—Senator Frum, for example—that there won't be any disclosure until after the election. There will be with this interim report, and it could disclose quite a bit.
This is done by leadership candidates in leadership races, the disclosure monthly and in the last week as well leading up to the leadership vote. I don't see why it cannot be applied to everybody. Voters have a right to know who is bankrolling every interest, candidate, party, and third party trying to affect the election.
