Nursing in canada

I am a nurse from singapore and my boyfriend (studying industrial engineering) and I hopes to migrate to canada in the near future. We arent really fussed about which part of canada but prefer ontario or nova scotia. I hope someone can give me advise on what is the best way of finding a job there. I understand that I can travel there for holiday purpose and look for a job and if i get it then the employer can apply for me a work permit. Is that the best way of getting a job or should I apply from here.

Another thing I hope to know is because my boyfriend has only a diploma in industrial engineering but is working as a AV technician inside a hospital now, would it be hard for him to get a job in canada as he does not have a degree. What would the best advise be for him?

Thank you in advance for your replies and I really hope to hear from anyone soon.
