We are coming up to Canada through Lake Champlain. We will be traveling on
the Chambly, Richelieu, Rideau and Trent Severn canals. We will also be
using the St Lawrence commercial locks in the canal on the southern side of
the river across from Montreal.

We have a mast of 28 ft high.

Will we be able to travel all of these canals with our mast up? If not,
where will we have to lower it?

Looking at the Rideau appears there are some low bridges, and the spec sheet
for the Trent Severn appears the same. They use the term "bridge clearance"
but do not say vertical or horizontal clearance, both of which are required.

Ralph,

The Chambly canal has to be "mast off", The Ottawa river, "mast off", The
Rideau, "mast off".

The seaway route "mast on" all the way from Montreal to all the Great Lakes.
