Working for a Canadian Company in Colombia

I work for a Canadian company and they have been contracting in Colombia for a while.
They asked me if I wanted to go to Colombia and with no hesitation I accepted,Por Que Mi!
Well I did a lot of travelling thru Panama, Colombia Equador and Peru in the the early 80s and enjoyed it immensely, except all that Narco shit going on.
For all these years since then I have been wondering if I would ever go back, well no more wondering I am going back and happy about it.
The Executive Administrator with the company emails me this list of things to do before I fly down to Bogota,
It is, get your Passport and AME licence Notarized and bring it to the Colombian Consulate in Vancouver and get it consularized so I did and they stamped it after I paid them and I haven't a clue what this is for.
Then the Administrator emailed me a ticket to Bogota, ONE Way to leave at the end of Nov.
Wow I thought is this the only thing I have to do and the Administrator said that she doesn't get involved too much with the details for the workers going off shore she only said that there was someone down in Bogota that will help you get your Work Visa and Cedula, Ok I thought so I will enter the country as a tourist that requires no visa and pay the reciprocity fee Canadians have to pay and away i go.
Sounds to easy does Anyone no any different
Do I show them my Consularized Document at point of entry or let be, cause I am going down there as a tourist and will get the visa later.
Sounds fishy maybe a return ticket would present no problems I don't know Help me if you can
Thank You
