The Candian Embassy published these guidleines for visiting Panama. First all Canadians must show a passport valid for 3 months beyond their expected date of return to Canada.
Tourists may only remain in Panama for a maximum of 180 days. If you wish to remain in the country after that time, you must change your residency status. If you attempt to renew your stay in Panama by travelling out of the country for a short period of time with the intention of returning to Panama as a tourist, immigration authorities may deny you reentry, as they are implementing stricter border controls.
Other entry requirements
You must obtain a correctly dated entry stamp from immigration officials upon entry into Panama. Failure to do so may result in a fine, as immigration officials have begun strictly enforcing entry and exit regulations.
Ongoing Ticket/Cash Requirements
When entering Panama visitors are required to have the equivalent of US$500 or a credit card, plus a return or onward ticket.
Canadians with a criminal record may be refused entry to Panama, even if it is only for transit purposes en route to another destination. Reasons for denial are generally for drug related crimes, money laundering, fraud or violent crimes. Check wth the Panamanian Embassy in Ottawa or the consulate oi Toronto if you are unsure.
Entry and transit permission restrictions are occurring with greater frequency at Panamanian points of entry, primarily at Tocumen International Airport.
Foreigners must register their biometrics (fingerprints and facial scan) at their port of entry.
