The comments all assume that the legal obligations between the airline and the ticket agent are the same in Uzbekistan as in the US or Europe. In the US and Europe, the passenger bears responsibility for the correctness and completeness of travel documents.

As @jpatokal mentioned in the comments, the visa center worker seems to be mistaken. The visas that have been affected in this change are Z work visas, M business visas, and F exchange visit visas. The normal letter from your friend will be enough, I suggest you make another appointment and if you run into the same problem ask to speak to management.

According to the answer on another question about visiting Canada, the Government of Canada provides a short questionnaire that helps you figuring if you need a visa and how long you are allowed to stay.
When filling the questionnaire with the information you provided, I could find that you are allowed to stay temporarily in Canada to visit without a visa. ...
Simple answer, Yes you can. Just make sure you get back to the airport before the flight.
If your flight is in one ticket, then you do not even need to pick up luggage and re-check it in (thanks to @jpatokal for the reminder). Just go out, enjoy your time :)
