Many Canadian gardeners grow topical plants outside in the summer months and successfully overwinter them indoors. You have already moved your hibiscus plants indoors well before the first frost as they would not survive outside.
If you were unable to do the following before you moved the plants indoors, you may wish to attend to these now. Check the plants for insects. Hibiscus commonly attract whiteflies. While outside it is good idea to give your plants a good blast with the hose before bringing inside to dislodge any bugs, particularly the undersides of leaves. It is also a good idea to remove any dead leaves and debris where insects may find shelter. Inside, you my be able to accomplish the same in a shower or bathtub with a shower hose.
It’s more than likely your hibiscus will lose its leaves shortly after being moved indoors and the blooms may not open up. This is quite normal. New growth will eventually appear. Hibiscus overwinter best indoors if provided with bright light and warm temperatures. Keep the soil consistently moist, but do not allow the plant to stand in water.
It’s a good idea to repot your plant with fresh potting soil in the spring before taking back outside. At this time, prune back all leggy growth that has appeared and begin fertilizing with a well-balanced fertilizer every two weeks. Your hibiscus can be slowly acclimatized to the outdoors temperature and into full sun after all danger of frost has passed.
Here is a link from the University of Maryland which provides more information on overwintering tropical plants, including hibiscus.
Good luck with overwintering your plants.
