G. G. F coy What does this stand for?

While reseaching my great grandfather's (Charles Thomas Brewer), WWI records, it shows he served 7 years in 'G. G. F coy'. Can anyone help me with this? I assume G G stands for Governor-General? He was born in New Zealand moved to England, then came to Canada and settled in Hull?, then moved to Vancouver. After the war they homesteaded in Peace River, Alberta in 1918. Thanks for any help, Ken

GG could be the GG Foot  Guards. They are an Ottawa regiment, and if he lived in Hull that could fit. F Company.

Ken, I looked at his Attestation Papers online, to me it reads GGFG, which is certainly the ONLY abbreviation for the Governor General Foot Guards.

Bill and Cliff, thank you so much for the info. It was hard for me to make out the abbreviation on his papers on line. For some reason I thought maybe he served in New Zealand, not knowing when he left there. I contacted them by e-mail, but he hadn't served there. Thanks again for filling in some more of the pieces for me. Ken

I saw your posting here, and as a person with a long association with the GGFG, I just had to respond!!
Had a look at Charles Thomas Brewer`s CEF attestation papers- as my eyes see it, it is not GGF Coy, but rather GGFG, with the last G shaped very much like the first/second G on the attestation paper.
My GGFG records reflect that Chas Brewer joined the GGFG as a private on 27 April 1896, and was promoted to Sgt on 4 April 1899. He was stuck off the regimental strength as of 5 May 1903. This reflects the 7 years previous service he states on his CEF attestation paper.
I hope this helps.
Cheers,
