I'll take that question. Thank you very much.
The statistics provided by Statistics Canada, from the Canadian Centre for Justice Statistics, do not allocate time to any procedure throughout the criminal justice process. Unfortunately, there aren't any statistics with respect to time.
There are a few statistics based on the number of preliminary inquiries. Juristat of February 2018 provides that number, and it relates to charges rather than cases. There are 34,698 charges, which ends up being 3% of provincial court charges.
