Good evening, I am sorry to hear of the difficulties that you are having.
Aside from any financial right dispute that might arise out of the matrimonial home, he does have a right of occupancy in the home since you both reside there and it is the matrimonial home. Although the house is in your name and you have a prenup which seeks to protect your financial interest in the home, he still has an occupancy right in the matrimonial home so it's not just a case where you can tell him to leave. Even the police could not make him leave.
If you wish him out of the house and want to occupy it on your own and remove his right of occupancy, you'll have to file with your local Family Court for an Order of Exclusive Possession. This would provide a legal declaration that you are the only one entitled to occupy the residence and your husband could then be removed by the authorities.
This is something that you can do without a lawyer, although having a lawyer is always preferable as there is a fair bit of paperwork to draft, serve and file and legal arguments will need to be made in Court. Still, you can do this on your own if cost is an issue.
Here is a link to a handbook published by the government for women leaving relationships of abuse and covers all of the related areas of law, including applications for Exclusive Possession. http://www.cleo.on.ca/sites/default/files/book_pdfs/handbook.pdf You will also find a lot of other related information that will be very helpful.
Here is another article on the issue of Exclusive Possession. http://www.sorbaralaw.com/exclusive-possession-matrimonial-home/
And another http://www.freshlegal.ca/blog/2015/1/3/exclusive-possession-of-the-matrimonial-home
So this is what you'll want to do to get him out of the home.
But you'll also have a long road ahead to deal with the rest of the fallout from the breakdown of the marriage and to protect your rights and ensure that the prenup is upheld, otherwise, he could end up receiving half of all property and you could pay him support.
Again, this is why it is so essential to have a lawyer represent you, because so much is on the line.
