True, and the Bank of Canada is doing what it said it would do. It's just well beyond the ability of the BoC to solve inflation on it's own. The best it can do is raise rates until we end up in stagflation, which I believe we are dangerously close to.
I also have to admit that many of the underlying causes of inflation are out of Canada's control, this is without doubt an international problem. Having said that, there is a great deal Canada still can do to influence inflation and the cost of living.
As an example, wrt housing, raising the interest rate slows demand, by making it harder for people to afford house, but it also slows building by reducing access to capital to actually build more houses (hence stagflation). This is why the BoC and interest rates are insufficient. However, the Federal government could get back into the business of building public housing. That right there would go a long way to reducing the cost of living. Would it solve everything? No. But it would help one aspect.
