Its the one on Sheppard Ave. I believe this is the only office you can go to for emergency marriage certificate. Once you go there and pay, call the CSR line and tell them that you need it ASAP for your emergency reason, they may give you the fax number to send the letter in. I don't have that fax number anymore, sorry. My emergency reason was that my husband is out of status and has a removal order in effect in which a spousal app need to be submitted ASAP but is pending because the marriage certificate is needed. Good Luck!!
