The SVFR minima in Canada is 1 statute mile (5,280 ft., or 1,609 metres), regardless of airspeed.
A factor which seems to have been overlooked by legislators is a 140 kt IAS with a 40 kt tail wind, (not uncommon), your ground speed will be around 180 kts. i.e. 3 miles per minute.
Yes, oddly, ground visibility in Canadian METARs are reported in statute miles, yet flight planning and distances on charts is in nautical miles. Elevations on charts are indicated in feet, yet Canada has officially been metric since 1975. What a country! The U.S.A. has only recently changed to reporting temperatures in Celsius on METARs..
