Caution Regarding Vertical Clearances

The Canadian Hydrographic Service (CHS) would like to inform you that some paper charts and BSB raster navigational charts contain some vertical clearances where the decimal point in the clearance value is missing. In those cases, the digits are accurate, only the decimal point is missing. The affected charts are the following:
