Government debt is very much like personal debt. If the economy expands, debt can expand too and keep the debt to GDP ratio at a reasonable level. Similarly, if my income increases I can I increase my aggregate debt and keep my debt to income constant. As long as interest rates and risk profile remain the same then debt servicing cost will stay manageable.

What is more important is what you are spending the borrowed money on. If I buy a house then it will become and asset as principal is paid and I wont have to rent and can be healthy debt. If I borrow money and spend it on video games, Doritos and Pepsi, that is not healthy debt. If a government borrows and spends on, say, useful infrastructure with long term benefit - that's good and becomes a long term asset. Trudeau is buying the government version of Doritos and video games. Throwing money at special interest groups, many of which are offshore.

Also, he borrowed and spent during economic expansion and ate up future fiscal buffer. When things went south, he borrowed more and spent more (generally viewed as necessary) but had already been borrowing and spending like a retard pushing Canada's debt into absurdity.
