At least Phase 1 will provide access from SkyTrain straight into the exitsng Mall. The Phase 2 and Phase 3 parts are off to the sides, so probably won't be as disruptive to the mall.
The Luxury Phase as Phase 3 makes sense - to gauge the success of the rest of the mall with retail tenants and the public before building that side.
Phase 1 seems to have 2 anchors (sub-sub-basement) and the 2 levels fronting the plaza.
So while Phase 2 is built (not much mall demolition involved it seems - just the former Zellers), there'll be those new anchors, plus London Drugs and Sears.
When Phase 3 is built, the Phase 1 anchors plus new anchor (and big boxes) at the north end may be open when Sears is demolished.
Seems like pretty reasonable phasing.
WRT that Phase 2 north anchor, I figure it'll be Sporting Life
Seems obvious with the tie-in to the community centre, a similar name is shown on the renderings and
there's even precedent for the "bridge" entrance shown on the plans with their Sherway Gardens store.
