Having a warrant doesn't mean that it's a valid warrant for the what police say it is for, nor does it mean that anybody at Uber's montreal offices is qualified to make that call. Locking down the computers until Uber's lawyers have had a chance to verify what the warrant covers and what access the investigators are entitled to seems like a fairly prudent security measure. If somebody showed up at your office with a piece of paper saying they were allowed access to everything on your computer, would you unquestioningly give them that access? Personally, I'd hope any services that I trust my data to wouldn't give up access without some verification that it's a legitimate request.
