But unless their contract specifies this, they are running a risk of a lawsuit ... as far as CIC is concerned, a valid visa waiver passport is enough on its own. A return ticket is not mandatory.

Standard conditions of carriage for every airline pretty much cover every eventuality, including not having or appearing not to have valid travel documents (section 7). I have come up against many who threatened law suits, but none who had actually read the conditions of carriage. Other than blatant discrimination, which I have not come across there is not much one can do if a carrier refuses boarding.

Heidi40. I have just applied for a travel document for my son, which I received yesterday. This follows his photographs being rejected for his PR Card. It took 10 days in all, including postage to and from London. I thought long and hard whether to apply for one or not based on what I had read on this forum. However, when you consider what could happen at the airport and the resultant costs if you were turned away from your flights, £35.00 + postage is a cheap 'insurance' policy.

There was a successful lawsuit in Australia some years ago against an airline who refused boarding due to lack of a return ticket (no legal requirement to have one).

Anyway, it's clear that if you are PR and want to avoid the travel document, it can absolutely be done with Air Canada. With a charter airline, you're taking your chances. Perhaps since Air Canada has many more flights to and from Canada compared to the charters, it has a lot more flexibility to deal with anyone refused entry.

Always a risk. At AC the same conditions as BA.
'Right of the carrier to refuse carriage to passengers who fail to comply with applicable laws or who fail to present all necessary travel documents.'

Sigh.

Air Canada is quite clear that those from non-visa waiver countries do not need travel document.
