It can be really difficult to obtain a visa when you are applying for a PR. It is not impossible but you will need to provide concrete evidence you will leave at the end of the trip.
How long of a trip are you hoping for, a short trip is preferred.
How much have you traveled, they like to see frequent short trips to similar countries.
You need to show you can support yourself on this trip, you also need to show why you will go back.
Canada's concern is going to be you will stay, what reason is there for you to leave? Your husband is here and you already have applied for a sponsorship. If he will also pay the entire trip and you are dependent on him financially there really is no incentive for you to leave at the end and just wait out your PR sponsorship from inside Canada.
