Christians with ethics and integrity don't generally seem to need to invoke their religion to prove it.  

I expect to be held to the same standard as any other GC no matter their gender, race, sexual orientation, religion or the host of other things people use.  

It says"To refuse to sell or rent after the making of a bona fide offer, or to refuse to negotiate for the sale or rental of, or otherwise make unavailable or deny, a dwelling to any person because of race, color, religion, sex, familial status, or national origin."

@Steve Vaughan thank you, no I dont believe in religion and I havent got much family.  

In DC I don't think you can ever legally discriminate in renting on basis of race, religion, familial status, or any of the other protected classes, etc., unless you actually live in the same house (for example, renting rooms to female students only).

Thomas S.As you acknowledged in response to Chris' post, you may not discriminate based upon nationality, ethnicity, religion, sex or sexual orientation, familial status, etc. in Canada.   

The Fair Housing Act The Fair Housing Act (the Act) prohibits discrimination because of race, color, religion, sex, national origin, disability, and\ familial status in most housing related transactions.

Bring religion into business. 

The goal of the Fair Housing Act is to ensure “no person shall be subjected to discrimination because of race, color, religion, sex, handicap, familial status or national origin in the sale, rental or advertising of dwellings, in the provision of brokerage services, or in the availability of residential real-estate related transactions.†With respect to people with disabilities, the Act serves to: * Give people with disabilities opportunities to choose where they want to live; * Assure that reasonable accommodations and reasonable modifications are made so that a person with a disability can secure and use housing as fully as a person without a disability

There has been no mention of race, religion, national origin, sex, age or marital status.
