On-street parking is limited downtown and elsewhere. Look for meters or signs allowing it (some will limit you to 3 hours between 7 am and 7 pm). Meters and time limits tend to be strictly enforced. Lots and garages around the city charge $2 to $5 per hour or $7 to $12 per day. There are a number of public garages around the downtown core and Byward area. Byward has a lot of parking stalls (just not enough for Saturday morning market!).
Overnight Winter Parking Prohibition
You cannot park a vehicle on a highway or road between 1:00 a.m. and 7:00 a.m. from November 15 to April 1, though in Ottawa this law is only enforced when Environment Canada forecasts an accumulation of seven (7 cm) centimetres or more of snow. However, they should be aware that crews might be removing snow from recent storms, although signs are always placed in the snow banks several hours ahead to inform the public.
