so i guess, if he just re-entered, the old visitor's record is now voided, and he is now a visitor for 6 months. if he did not receive a visitor's record or a stamp in his passport with an exit date written, then it's safe to assume the OP's husband does not have to do anything about his status until his 6 months is almost complete.
We have travelled to the U.S. and back two or three times a year for the last two years with a Visitor Record (VR) in my partner's passport. Each time, they unfold it and look at it, see that it's still valid and hand it back. There is no evidence that re-entering voids a VR that's currently in place. It does say, "Does not authorize re-entry," but this merely means that the VR does not give you the right to re-enter. What it does do is tell you by what date you have to be out.
I called the CBSA help desk yesterday to ask whether my partner re-entering with a VR in his passport last month gave him permission for six months from the new date of entry, since his VR expires today. While entry points to Canada deal with "customs and immigration" questions, she was only prepared to discuss customs questions, but did tell me that visitors can only stay in Canada for 6 months out of every year. So, she said, if they've already been in Canada for 4 months, their next visit can only be two months. We sent off our extension request today electronically, so he should be on implied status until we get a reply from that extension.
This is our sixth request for extension. Hopefully, we will get a reply on the PR application very soon.
