You're absolutely right that interest rates are at an all-time low and that certainly makes these kinds of investments a lot less costly than they would otherwise be.
I'll note that we're really not alone in Canada in this kind of a response. This is the kind of advice we've received from the IMF and the OECD. It's very consistent with what all other major economies are doing in terms of seeing that value and providing support to businesses and individuals in order to avoid longer-term economic scarring that might indeed be more costly over the long run.
