TORONTO —

Transportation Minister Jim Bradley says Ontario will be able to provide enhanced driver's licences as an alternative to a passport before June 1.

Transportation Minister Jim Bradley says Ontario will be able to provide enhanced driver's licences as an alternative to a passport before June 1.

That's the day the U.S. will require Canadians to carry a passport or an approved alternative when crossing the border by land or sea.

But officials say an enhanced photo ID for the estimated four million residents who don't drive won't be ready before the new rules take effect.

Bradley says the high-tech driver's licence will cost an additional $40 on top of the $75 licence renewal fee, compared to a passport, which costs about $87.

He says he can't provide the specifics of how long it will take to get the new licence, but says the vetting process will require an interview.

Critics have complained the cards will trample on travellers' privacy and leave them vulnerable to identity theft.

The cards contain a radio frequency identification device that can be scanned at border crossings.

Each card transmits a unique number that identifies the traveller and can be used to access their private information.

Bradley says the licences will come with a protective sleeve that will help block the signal when the card isn't being used.
