Most calibration equipment cannot be calibrated in Canada unless you work for a national laboratory. Instruments will likely be shipped to an American calibration centre such as the one in Texas (Transcat).
Recent prices for a Datron 1281 calibration is somewhere around 2300 CAD to manually calibrate each range with data. A 3458A or a 6581T will cost about 1300 CAD to calibrate based on a resistance and voltage standard with data.
Good luck.
