About two thirds of people polled said the Union Pearson Express airport train will be too expensive.

The poll, conducted by Forum Research, asked 1,001 random Toronto residents how likely they were to use the high-speed airport train, which is set to enter service next spring. The one-way adult fare will be $27.50 ($19 for Presto card users) with discounts for seniors, students, families and airport workers.

Sixty-nine per cent of poll respondents said the fare was too expensive, while only 23 per cent responded that the fare was "about the right amount."

The poll also asked how likely respondents were to use the UPX service, which will connect Pearson airport with Union Station with stops at Bloor/Dundas and Weston GO stations.

The poll found that 40 per cent said they were "not very likely" to use the high-speed train while only 18 per cent said they were "very likely" to use it.

The airport train promises 25-minute service between Pearson and Union Station, with departures every 15 minutes.

The UPX website says the service will be running in time for the July 10 to 26 Pan Am/Parapan Games, which Toronto is hosting.

Some critics have said UPX fares are too high to attract riders away from using taxis, particularly groups of people travelling together. Officials from Metrolinx, the province's regional transit planning authority, have said fares are in line with similar dedicated airport trains in other large cities.

The poll was conducted on Dec. 17 and 18 and is considered accurate plus or minus three per cent, 19 times out of 20.
