The only one I will deal with is the CBC article.
In Canada, the Canadian Mortgage and Housing Corporation
http://www.cmhc-schl.gc.ca/en/co/moloin/index.cfm insures the majority of residential mortgages. Therefore, the Government of Canada is on the hook if the Bank that issued the mortgage calls the loan. By buying the 25 Billion dollars worth of mortgages, the Government of Canada removed the Banks from being able to make a decision that would have required the CMHC to pay the insurance on those mortgages. It's interesting to follow the comment over time. Let's start with your link

http://www.canadianrealestatemagazi...-root-of-canada’s-housing-bubble-garth-turner where the writer points out that buying 25 Billion dollars of mortgages the Harper government was able to control the release of the property in genuine distress into the market. The Harper Government (horrors) made money and Canada didn't suffer a severe puncture of the "Housing Bubble". In the lower mainland, there is a slowing of the market - but - not a drop in the selling price.
Contrast that to what happened in the USA where the money was given directly to the Banks who then paid bonuses and socked the remainder away in tax havens. The USA has millions of houses that were foreclosed on and houses in Florida, Nevada, Arizona and California are only worth a third of their 2007 value.
The Harper Government did it the smart way. The Obama Government did it the dumb way.
On Credit.
I've dealt with the same Bank for a very long time. When I recently purchased a house for current rental/future re-development, my bank competed vigorously to offer a mortgage on 50% of the house's value. They gave me 4.3% on 15 years with me having the ability to double my payment each month without penalty.
Contrast that to the woman on the CTV video who closed her Chase bank account to support the wall street protests.
She will have to open a new bank account and she will have to do it before she can cash her paycheck or pay bills. If she needs overdraft protection or a credit card, she is now applying for a "lender of last resort". Her overdraft protection will cost 9 - 15% and her credit card will cost 18 - 28% if they are willing to give her one at all.
Why was Chase heavily targeted by the protesters? Because Chase sucks. Chase was waiting until a service person was deployed before sending a letter demanding payment of their mortgage - even if the service person wasn't behind on their payments. Chase knew that it would be impossible for a service person on a 6 month deployment to be able to deal with the issue before they could legally grab the house.
Yup - that's the kind of Bank that it was important for the Obama Administration to "save" by giving them money to sock away off-shore. That's called Return on Investment for Chase who only gave a couple of million to the Obama campaign.
