Your questions, answered.
Is Mainhaven in Stittsville or Kanata?
The official community overview identifies Mainhaven with Stittsville in Ottawa. Mattamy lists its sales service at 1020 March Road in Kanata; this is separate from the community location.
What is near Mainhaven?
The builder highlights Trans Canada Trail, Bell Sensplex. These are area destinations, not promised facilities within the development.
Do floorplans confirm an available home?
No. A floorplan describes a home design. Only an individually identified builder listing represents an advertised home, and its current availability and terms still need confirmation.
