There are two questions: what defines a large project, and how long might it take for small procurements.
The Government of Canada, through Treasury Board, has a policy that details what makes a major crown project or not. One of the key criteria is that it's over $100 million.
That being said, depending on their nature, there are certain projects that one would decide are major projects. So there is some variation related to that.
Regarding other types of procurement, of course you could procure in a day. Our aim is that all the off-the-shelf goods and services that the government has a need for on a daily basis could be accessible within 24 to 48 hours. We have a whole series of instruments--standing offers, contracts--that allow that now, and we do have the intention to do much more.
