With the bond market yields rising due to concerns about China, Ireland, etc. TD Bank was the first major lender today to increase mortgage rates on terms one to five years. It appears that the 5 year fixed rate will still be under 4% but there is a big jump from where we are currently.
As of this post, no other lenders have matched the increase so there is still time to lock current rates in. However, the window of opportunity is very small so I would suggest you do it now.
