I live in Ontario, Canada so I am interested to know what the laws are pertaining to me only, and not any other province or the States.

My husband has 2 children with his ex, and the mother has sole custody (despite my husband's attempts to keep joint custody). His ex is flipping out because we recently had to move into a smaller house and no longer have an extra bedroom, so we have the 11-year-old boy and 9-year-old girl share a bed when they visit us every other Friday and Saturday night. The mother is saying that she is going to call Children's Aid on us and that we are not acting in the best interests of the children. Can someone please let me know if this is really an issue? What if we get them to sleep in separate sleeping bags on top of the bed? I understand that maybe the boy is embarrassed to wake up next to his sister, being as he is at the age where he is starting to hit puberty.

Any insight would be greatly appreciated. Thanks a bunch!
