There are some methods that we do not yet fully have replacements for. Developmental neurotoxicity is one of those examples.
What we need right now is to adopt everything that we have available at our disposal. The entire tool box of new approach methods that we have at our disposal needs to be incorporated into every protocol and every procedure possible. At the same time, invest big time into developing these technologies where we are lacking them. That is where we are lagging behind other countries as well. The United States has spent hundreds of millions of dollars on the development of these new methods.
I don't think the Canadian government has done nearly enough—actually, it's not done enough at all—to move this field forward by investing in the development, validation and acceptance of these methods.
