A Canadian airport has come under fire after turning some of its 'disabled-only' parking spaces into 'Lexus-only' spaces.

The Calgary Airport Authority sold five accessible parking spaces to the car company, which painted its logo on the floor and only allowed Lexus drivers to park in them.

But their plan fell apart when a family with access needs arrived at the airport, only to discover their parking spaces had disappeared.

Calgary Airport Authority spokesperson Jody Moseley says the disabled parks were sold to make money.

"We're always looking at different ways to diversify our revenue stream," she told CBC News.

She blamed the family's lack of accessible parking on bad timing.

"I think it was one of those communication fails," she said.

"We really were in the process of moving and accommodating the new advertising space at the same time, but what we really should have done is let them know in advance that this was happening."

She says more accessible parking spaces have now been added to the airport.
