Hotel Room Reservation Blocks

CADSI works with hotels in Ottawa to provide you with special rates. Room blocks will be announced in early 2018. CADSI does not use a housing bureau or third-party agency for hotel accommodations or any other travel arrangements. Please book directly with a specific hotel.
