Whiting to autosport.com:
"The DRS zone will be on the last straight and the pits straight," said Whiting when asked by AUTOSPORT to confirm where the two zones will be in Canada..
"There will be one detection zone. The initial detection will be after Turn 10, then they can have another go [on the main straight]."
Emerson Fittipaldi will be this events race steward btw.
