This is an interesting question. My situation is that my outland PR application was refused and our case is in appeal. I had been in Canada the entire time with legal visitor status, but after the PR ap was refused, they refused to extend my temporary status and told me to leave Canada. The Minister of Immigration overruled that decision and issued a TRP that allows me to stay in Canada for another year - so our appeal can be settled and hopefully PR granted. I've been told that the TRP will not prevent me from getting PR if our appeal is allowed. So the first question would be: is your husband's inland application still in process? You should be able to find that out by contacting the Call Centre.
Second thing: I know that someone in Canada on a TRP is not eligible to apply under the permit holder class until they have been in Canada on a TRP for three years.
The big question is: is someone in Canada on a TRP eligible to be sponsored as a spouse? I was under the impression that the answer to that was "No". I was thinking that, if our appeal fails, I would not be eligible to be sponsored as a spouse under a new PR application unless I give up my TRP status - but now I'm not sure why I've been under that impression. So hopefully someone who knows for sure can enlighten us both and provide some links to resources in the Act/Regulations or the processing manuals.
