Considering the EU-Canada trade deal took 9 years, and thats just trade. Brexit is going to take considerably longer to negotiate as its a lot more that needs decided on. Tentativley i recon to fully Brexit it will take at lest twice that and the relationships are so deep that it might even never complete (NI-Eire border etc.) and adequacy is going to be a hard sell as the people that decide it (Article 29 Working Party) have always had issues with how the 1998 DPA implemeted 95/46/EC and there are more concerns that were brought up in the article.
There are already some lessons learned for the next EU exit process (probably Grexit or Itexit), article 50 will be modified to: anyone wishing to leave must agree a transition period which must end as the next EU budget cycle begins, or extend their membership for another budget cycle.
