It certainly does, and the 5ft sheets I use are probably made in Canada. You might be able to find a local cabinet shop order one for you. Any plywood distributors will have them in stock, but often will not sell to the general public.However 3/4 inch MDF does not come in 5 foot wide sheets (At least not here in BC, Canada).
According to the specs, the machine can only cut a 52"x52" area. What I would do, is use two pieces, with a seam over one of the beams. Then add a second layer that just covers the usable area, as you'll need to surface this are flat.
