Thank fuck my mortgage rate is locked in. I refinanced when rates were at rock bottom, I'd hate to see what my mortgage payment would look like today if my bank was allowed to raise it.
That's the Canadian system, have to renew your rate every 5 years. It's great for the banks. The tighter regulations helped Canada avoid the underwater mortgage fiasco of the US in 2008/2009, but mostly it's just a really good deal for the banks. :)
