Well, a novitiate such as yourself might begin with this piece for Canada's National Post (this is the article that really got the CANZUK ball rolling in Canada). https://www.google.com/amp/s/financialpost.com/opinion/from-brexit-to-canzuk-a-call-from-britain-to-team-up-with-canada-australia-and-new-zealand/wcm/11fe6411-03e8-4a7b-b6e3-cc9cbe2cd781/amp/ https://twitter.com/bo66ie29/status/1329039455676747780
Next, for those like @bo66ie29 unfamiliar as yet with the basics of CANZUK, you might try the following piece on the many areas in which the CANZUK countries can work together in a geopolitical partnership: https://www.canzuk.co.uk/single-post/2017/03/08/LIlico-In-what-areas-might-the-CANZUK-countries-work-together
Next you might check out this piece which explores how universally popular with voters (including in particular younger voters) some of CANZUK's dimensions are: https://reaction.life/conservative-party-needs-canzuk-migration-deal-attract-young-voters/
If you were curious as to why CANZUK should include just those countries & what other countries might one day (perhaps decades hence) join, see this: https://www.canzuk.co.uk/single-post/2017/03/10/Lilico-What-other-countries-might-eventually-join-CANZUK
