Please read the OP's post. She doesn't have to apply for residency, she's a citizen. You're partially right, of course, in that a visitor visa is likely to be denied.
Like Shehzad said, it's hard for spouses of people who are in Canada to get visitor's visas. Visitor's visas are not supposed to be used to end-run the PR sponsorship process. You can - and should - apply for one and see what the result is. You are most likely going to be denied.
If your husband gets a visa and is comfortable with coming to Canada and not leaving for the roughly twelve months it takes to do a sponsorship, you can do an inland application. Be aware he may be turned around at the border if it looks like he's moving to Canada. If he gets in, he should not leave until the application is processed because he may not be allowed to return, and if he is not allowed to return, the PR application is abandoned.
If your husband is denied a visa, you would apply outland. It would take about a year to process the application.

By residency this meant PR for her husband which she was asking about.
