Canada's health care system is in some trouble and costs are rising due to various issues, but it is not in danger of "collapsing" into the mess that the US had, or is currently working towards. The wealthy often do go to the US and elsewhere for more timely treatment of critical illness, but if anything that relieves pressure on the domestic health care providers (and they still have to pay taxes and subsidies into the healthcare system regardless).
And don't use our wealthy going elsewhere for treatment as proof that our system is flawed and incapable of supporting itself, because many US citizens have been dependent on the cheaper prescription drug orders to the US being filled by Canadian pharmacies, legal or otherwise.
Lack of housing bubble: As much as our current Conservative government loves to trot out our more regulated banking system as the beacon of hope to the world, they actually were trying to follow the US in deregulating banks. The only thing that stopped them was that they had a minority government at the time, so the opposition parties prevented that from happening, saving us from the 2008 housing bubble burst.
