Technically yes. The occupation "bartender" is not listed as an eligible occupation under AINP but "bar service waiter", "beer server" and "coctail waiter" are included under NOC 6513 which would also include bartending in my opinion.
NOC 6513 - http://www23.statcan.gc.ca/imdb/p3VD.pl?Function=getVD&TVD=122372&CVD=122376&CPV=6513&CST=01012011&CLV=4&MLV=4

That said, this occupation is listed under "Hotel and Lodging" which means you might have to be a bartender at a hotel to be eligible. Furthermore, you might be held up to the "employment requirements" listed on the NOC website which are one/two-year vocational education etc.
Your employer, even if a hotel, would need to satisfy the requirements listed under "employer requirements/eligibility" on the AINP website.
Now that you know how they scrutinize your application in relation to the requirements listed on the relevant websites, you can do the research to find out if your case meets the requirements or if you need to look for a job that does so that you can apply.
Good luck!
