Your money. Their junk mail.

I stand corrected: it isn't just Con MPs who have apparently been told to take every possible opportunity to use public money for the party's political gain. Instead, the unelected, unaccountable Senate is also being converted into a Con distribution centre:

Conservative Senators are quietly using taxpayer-funded literature to target opposition ridings with a partisan crime message as the party gears up for the next election, the Toronto Star has learned.

And at least one of the Senators sent the mailers out at the direction of the Conservative Party of Canada’s national campaign office.

That Senator was Bob Runciman (Ontario). It is not clear whether Senator Don Plett (Manitoba), who distributed almost identical material, did so at the behest of the party.
...
By using the Senators to send out this kind of literature, the Conservative Party gets around the prohibition on MPs using tax dollars to send partisan messages to other ridings, which the House of Commons agreed must stop.
