It took a lot of sleuthing to figure out the correct TCT hiking route across the North Shore. The most accurate and complete information seems to be in the Google Earth kmz file found on trailsbc.ca which I have converted to gpx format. The interactive map on the national site tctrail.ca is inaccurate and incomplete as are some of the other sources on the provincial site. The TCT continues south down Mosquito Creek bypassing the marina and eventually intersecting with the Spirit trail to the east.
There are a total of 5 peaks along the Needles / Lynn Ridge with the most direct approach for all being from Hydraulic Creek. The generally recognized main summit of Lynn Peak is the one immediately south of the Hydraulic Creek drainage (the north peak). The one immediately beyond the viewpoint at the top of the Lynn Pk trail is referred to as "South Lynn Peak" on bivouac.com.
