A late goal from Fredy Montero grabbed a road point for the Sounders.
The Whitecaps spent the majority of the first half in the lead. Alain Rochat gave the home team the advantage in just the 12th minute with a run down the left flank and a calm finish on the end of it.
That goal held up until just after the break when Eddie Johnson pulled the Sounders back level with a header. Mauro Rosales was played in down the right and floated in a cross for Johnson to nob back across goal and into the net.
The Whitecaps went back in front in the 82nd minute through Camilo, who curled a free kick into the back post from an odd angle after it went across the face of goal untouched.
With it looking like the home side would get out with all three points, Montero popped up with a lovely finish to earn the draw from Seattle, taking down a flicked header from Johnson and evading a tackle before bending his shot into the goal.
