This page is now an August 2016 re-write based on further information provided by Parks Canada on the scope of the infrastructure program work


A basic requirement of any cultural World Heritage Site such as the Rideau Canal is to maintain the structures that are integral to its designation as a World Heritage Site. For the Rideau Canal that is both the structures that maintain it as an operating canal (locks, dams, weirs, canal walls, bridges) and structures that relate to the heritage aspects of the designation (blockhouses, lockmaster's houses). It is also a requirement for any National Historic Site (the Auditor General in 2003 pointed this out in spades - Parks Canada has a responsibility to maintain the structures that relate to its National Historic Site designation).

The Government of Canada has made significant in-roads in addressing this problem with a $46 million infrastructure program announced in June 2015 and an additional $57 million announced in May 2016.

This funding has now addressed all the heritage structures that were listed as being in poor condition in the 2012 National Asset Review (PDF) although work on several assets for which deferred work was indicated (i.e. Davis Lock) have not been funded.

There also remains a significant problem with base capital funding - the Rideau Canal still does not have sustainable capital funding (see bottom of page of a chart of historic numbers). This remains to be addressed so that we don't end up, 20 or 30 years from now, with the same deferred work problem that the current infrastructure program is partially addressing.



Commemorative Integrity

There is a problem in that some of the infrastructure work is threatening the Commemorative Integrity of the site. View the Commemorative Integrity page for a full definition of what it means, but in a nutshell it is the built heritage of the site that relates to its construction (i.e. locks, dams, weirs) and the heritage landscapes of the site which includes everything from viewscapes to overall heritage appearance.

One of the things that threatens the heritage appearance of the site is the use of modern materials for repair, these have a cumulative impact on the historic character of the site. We now have several recent examples of where this has and it may become a bigger problem as the infrastructure work continues. Examples include the "short term" repair of the quoins at Jones Falls done in modern white cement with straight, regular lines. This clashes with the heritage view of the locks (and prompts the very first question I get on every tour I give of Jones Falls - "why do those look so different?"). There is a bit of an excuse for that one since a "short term repair" can only be done with a planned "long term heritage appropriate repair" - and, in theory, that long term heritage appropriate repair will be done if Parks Canada is to follow its own rules.

More recent examples include the 2011 repair to the weir at Jones Falls, done in ultra modern cement (white, straight lines) and includes modern features such as an aluminum staircase (fits okay in a modern factory, not so much on a heritage site). That work, which is in full view to the visiting public, is in contravention of Parks Canada's own Commemorative Integrity policies.

Same goes for the 2015-16 work at Poonamalie where the Minnow Creek Weir was done the same way. It would have taken little effort to try to emulate the original character of the weir, but that was not done - ultra modern white cement was used, with straight lines and a stripped apart open landscape. It completely changed the character of the site. If Jones Falls is any indication, the cement will not "soften" over time. It is in full view of the visiting public, the heritage character (commemorative integrity) of the site was not taken into account in the design of the work. Engineering goals and heritage character can work in harmony. In fact in any planning, the engineering design must take into account both the ecological and cultural commemorative integrity of the site - this wasn't done at Poonamalie.



Sustainable Capital Funding

So that we don't repeat the roller coaster of letting heritage structures deteriorate to the point where huge injections of cash are needed to save them - yearly, steady, and predictable capital funding is required. That means a consistent and sustainable capital budget for the Rideau Canal. There is no history for this, it's never happened, but if we look to the past, when Parks Canada took over the Rideau Canal, they were spending a lot more than they are today (in 1975 the number was $13 million (in 2015$). While we're not likely to see that again, we clearly need a lot more than the 1 to 6 million that has been allocated in the recent past, since those numbers are not sufficient to sustain the heritage assets in good condition.
