Transport committee  My experience is a little different from the previous witness. In the six municipalities, we worked very hard on one major challenge, that of locating the service entrances. We do not know where the lead is. In some cases, we do not know either in the private areas or the public

Transport committee  I would like to add that it would be important to consider any policies to accelerate the replacement of the lead service lines both on the public side and on the private side. We had 21 utilities sharing with us the difficulties and the barriers to getting this private side fund

Transport committee  It's an excellent question. I have students working on this right now. There are no studies except one old European study that measured how much lead was in there every time somebody took a glass of water or used water for cooking. You would take a subsample and you'd see over a

Transport committee  Last year, Ms. Deshommes published the results after a five-minute flush and after the water stood for 30 minutes and 6 hours. The simulation took place during one night. The differences are considerable: the concentration can be almost double. A sample taken after a five-minute

Transport committee  Perhaps I could offer a partial answer to your question. I was involved in drafting the Ontario regs. Yes, there's quite a bit of difference among the regulations in the different provinces. To give you a striking example, the Quebec regulation calls for a flush sample; you let

Transport committee  It is a federally regulated standard. It's not an MCL, like it is in Canada and in most provinces that have moved ahead. It is a treatment. It's an objective, an action level. It's very different. But that standard or regulation, the lead and copper rule, is being reviewed as we

Transport committee  You're asking an academic to delve into politics. This is not in the script.

Transport committee  Putting on the hat of a mother and grandmother, I would like to be sure that young children across Canada are not exposed to lead. Whatever shape and form every regulation takes, I don't really care, but I would like the local regulator and provincial regulations to address the h

Transport committee  I would argue that Ontario should be considered as a model. They went ahead with a more recent regulation. It's very similar to the one being used in Europe. The new guidance from Health Canada is somewhere on the next step to that, and it's very similar as well. I would certainl

Transport committee  Yes. On the impact of partial lead service line replacement, we have conducted two series of studies, both of which suggest that partial replacements are not the preferred solution, but they do not cause an increase in the amount of lead over the long term. This is an important

Transport committee  Good afternoon. I'm a professor of civil engineering at the Polytechnique de Montréal, where I hold an industrial chair on drinking water, co-funded by NSERC and by the utilities in the greater area of Montreal that are serving about three million customers. I've conducted rese
