So many Locks

While the major lock systems connecting the Great Lakes are impressive, there are dozens of smaller locks connecting the hundreds of lakes and rivers across Ontario. Your could travel for weeks across these waterways which are now used more for pleasure than their original requirement to facilitate trade. The locks come in a wide variety of forms. At Peterborough, they have the world’s highest (at 20m) hydraulic lock which uses a counter-balance system to raise and lower boats (along with a heap of water).もっと詳しく
