Excimer, on my reading of Bill C-46, it still requires the police to have "reasonable grounds to suspect that a person has alcohol or a drug in their body and that the person has, within the preceding three hours, operated..." in order to take a breath sample.

What appears to have been removed is an intermediary step to require coordination tests where the officer thinks the driver is drug-impaired.  That step was never required for alcohol.

No doubt the amendments will become more clear during second reading.  I stand by my comment that calling this "another step in Justins march towards a police state." is "a little dramatic."
