As there are hundreds of thousands of lakes your question is impossible to answer.
Hurricanes can come to Ontario, although that is rare. We did have Hurricane Hazel in 1954.
The Niagara River flows northerly from Lake Erie to Lake Ontario. It is 35 miles long and the border between the USA (New York State) and Canada (Ontario Province).
It is impossible to accurately answer how many gallons of water are in a lake. The depth constantly varies, as do the levels. However, based on averages, a rough estimate can be given. Lake Okoboji has a surface area of 3,847 acres and an average depth of 39 feet. There are (rounded) 325,851 gallons of water to an acre foot, or one acre covered in one foot of water. Based on the size and average depth of the lake, there would be somewhere in the huge neighborhood of 48,888,403,083 gallons of water in Lake Okoboji.
Using the depths of 1332 and 802 feet respectively, Lake Superior is about 530 feet (161.5 m) deeper than Lake Ontario.
(Lake Ontario's surface height above MSL is more than 350 feet lower than the height of Lake Superior, as evidenced by the intervening Niagara Falls.)
The major settlements near Lake Ontario are:
There are many Canadian cities on Lake Ontario. The major ones are Toronto and Hamilton, but here is a complete list:
Niagara Falls is a collection of three waterfalls on the Niagara River as it flows northward from Lake Erie into Lake Ontario. There are actually three separate waterfalls. The smaller two, Bridal Veil Falls and the American Falls, are located in the US, while the iconic Horseshoe Falls is also called the Canadian Falls because it is located in Canada.
The temperature for a lake depends on its location, depth, size, and season. For a more accurate answer, it would be best to designate which lake you are referring to, or at least a general location.
The Volume is more than the length
It is the Saint Lawrence River that connects Lake Ontario to the Atlantic Ocean. The river flows through both Canada and the United States.
I intend to drive round lake Ontario anti clockwise starting and finishing in Mississauga, using main roads. thank you.
the highest during the summer. ... From October through February, wave heights of 5 feet or more can be expected 10
Waves as small as one foot can be surfed, though larger waves can make for longer rides. The largest waves on the lakes easily surpass 10 feet, and waves more than 20 feet are occasionally recorded by NOAA weather buoys, usually in spring and fall. Even bigger waves are possible under extreme conditions in open water, though there's a general agreement among meteorologists that 25 feet is the upper limit."
Lake Ontario empties into the St. Lawrence River at the Thousand Islands.
