Hi Harkiran,
If you get the PPR in Dec 2016 your husband could wait in India for about 6 months which is June 2017 after the Passport has been stamped to fly in Canada.
Yes your family can collect and physically mail the PR Card to you in India and then you and your husband can travel back together.
My mother had to leave the country before she got the PR Card, so we met with a MP and got a support letter from him to later apply for the TRAVEL DOCUMENT to enter Canada. She also applied for TD, but we received her PR Card in the mail and FedEXed her the card with the highest security and urgency. She had to pick the Card up in Mumbai at a Fedex HQ which was the only catch.
Hopefully this helped.
Good Luck
