You are a Canadian citizen and you may live with your husband in Doha during the processing of your sponsorship application. If the CIC comes to know, they may ask you to provide proofs that you intend to return and reside permanently in Canada. If your parents or siblings are settled in Canada, ask any of them to furnish a letter making commitment to accommodate you and your husband initially when your husband land to settle after PR processing. furnish your bank statements and tax returns to show that you maintain your link with Canada. If you own your own house/ apartment then you will be in very safe side.
If you live together with your husband, it will show that your relationship is genuine.
I'm not sure whether this may delay the processing or not.
