I went home to Canada for the summer and yes, we brought our DH with us. I initially didn't want to but my hubby thought it would be good to have an extra pair of hands and also pointed out we would be paying her anyways, so why not have the extra help. In our situation, though I did need her since my hubby was only with us for 1 week and also couldn't fly back with us. (3yr old & 1 yr old). It was nice to have the extra help. More and more people are having helpers in Canada, I particularly noticed it when I enrolled my son in a swimming class and realized that there were alot of helpers present. So, it's not 'uncommon' as it once was to have a helper. Besides, my family and friends had also 'welcomed' the extra hand/help.
To answer the question: if you don't bring your helper, you still need to pay her salary, and if she is not staying in your house you need to provide room and board(ie at a boarding house) for the time you are away.
