Do you have condition 51 on your COPR? If you had applied for PR after October 2012 and you were not already together for 2 years and had no children together, you might have that. If you do, you were supposed to cohabit with your husband for at least 2 years after getting your PR.
Whether you do or not, you can still attempt applying for a travel document. If you do have condition 51 on your COPR, you can prepare for trouble as you have not been living with your husband for the past year. If you don't have condition 51, then you don't have a problem. Just give any address you want.
Once you are in Canada, you can tell your husband that he must surrender your PR card or you will report it stolen. If he doesn't, you should go to the police and report it stolen. They may help you get it back from him. If not or he says to them he doesn't have it, you report to immigration that your PR card was stolen, you have the police report and you can request a new card.
