Vancouver Mortgage Rates Going Lower?

I can not bellieve that these rates are heading in this direction, LOWER! We just got sent new rates from one of our lenders and we are now back at prime -.40% which is equal to 1.85%!! This is now the lowest that they have been offering on mortgages. Not sure what this new pricing means as far as direction of rates. In my opinion the banks have a lot of cash stored up and will need to get it out, in mortgages?
