I am married to a non-Canadian and does not live in Canada, how do I file my tax as "Married" but separately with my spouse since I am not claiming any benefits for my spouse as he is no ties and not a Canadian?

I got married to a non-Canadian who still lives and works aboard, while I still live and work in Canada. I changed my marital status to "Married" and even though I specified that I will be filing the income tax return separately, but it seems that his benefits are added to my return which I don't want to claim as my husband is not a Canadian and does not live in Canada.
