Where to get completion of working hours in Canada?

Hi guys question here. Im a Filipino Nurse but doesnt have workng experience yet. See its really hard to find work in our country these days bec there's just TOO MANY nurses and the hospitals here cant absorb us all. Anyways my husband was able to find a work in Canada and luckily I'll be going with him too. now the problem is i want to apply for a licensure exam in Canada. I am aware that i still need to have my credentials assessed first before i can apply for the exam plus the IELTS thing and other requirements but what i am not aware of is with regards to the working hours i have to complete before i can sit for an exam. do they have like an Interim Permit in the US wherein they would allow applicants to work temporarily while waiting for the exam thus allowing them to complete their working hours? or like can i work as an assistant or maybe even as volunteer in Canada so i can finish the said working hours? is there any possible way that i can complete the working hours without leaving Canada? Please shed some light. Much thanks.
