Thank you for your reply. I can't copy the CIC link (i copied it by replacing dots by dash) here but i have pasted the info from the link below. According to this info, my husdnand should be eligible to apply for the open work permit. Anybody has similar situation as mine/ anybody took this way to apply for their spouse's open work permit?
Why can't my husband apply for the open work permit as a spouse of a skilled worker?

Types of work permits for your situation
You're a spouse or family member of someone working or studying temporarily in Canada
You may be eligible for an open work permit if you’re:
• a spouse of a skilled worker in an occupation under the National Occupational Classification (NOC) skill type 0, A or B approved to work in Canada six months or longer,
• a spouse of a foreign student at a public post-secondary school, such as a college or university or collège d’enseignement général et professionnel (CEGEP) in Quebec,
• a family member of a foreign representative, or
• a family member of a foreign military member who is working in Canada.
If your spouse has an open work permit (e.g. post-graduation work permit), you must attach a copy of your spouse’s work permit to your application for an open work permit, along with:
• a letter from your spouse’s current employer that confirms they work there in a NOC 0, A or B occupation, or a copy of your spouse’s employment offer or contract, and
• a copy of your spouse’s recent pay slips.
