Envelopes for T7DR(A) remittance voucher

I used to be able to order envelopes from CRA with the 875 Heron Road address. Tried to order today but CRA agent said he could not find it. Maybe they are not being produced anymore as CRA is encouraging online payments. Has anyone ordered these envelopes this tax season?

They use that to pay at a bank
