The use of Official tags is a requirement under the Seeds Act (R.S.C., 1985, c. S-8) and Seeds Regulations (C.R.C., c. 1400); every lot of pedigreed seed sold in Canada must be labelled with an Official tag either "issued or approved'' by the Canadian Food Inspection Agency (CFIA). The CFIA provides tags to Registered Seed Establishments (RSE's), who may use the tags under the supervision of the CFIA. The tags are used for both the domestic and international movement of pedigreed seed.
