no its not legal. you are basically lifting an axle by removing a wheel.
Lift axles
7.11 (1) A person must not, without a permit, drive or operate on a highway a vehicle or a combination of vehicles in which a control is provided for varying the weight on an axle or group of axles, unless
(a) the control locks or unlocks a sliding fifth wheel coupler,
(b) the vehicle is a ready mix concrete truck and the control is manually operated and located outside the driver compartment and immediately adjacent to the axle or group of axles being affected, or
(c) the control is an automatic axle lift device that
(i) was installed on the trailer by
(A) the original trailer manufacturer, or
(B) an installer working under the supervision of, and according to an installation plan developed by, a professional engineer, and
(ii) is equipped with tamper-resistant features to prevent unintended field adjustments,
and the trailer on which it is installed
(iii) has affixed on each side, near the affected axles, a unique logo indicating that an automatic axle lift device is installed on the trailer, and
(iv) is equipped with an on/off control to operate the automatic axle lift device and with a status light visible from the cab to indicate to the driver when the device is activated.
(2) A person must not, without a permit, drive or operate a vehicle or vehicle combination with lift axles in contact with the ground if the vehicle is
(a) not also equipped with an automatic lift axle that meets the requirements set out in subsection (1) (c) (i) and (ii), or
(b) a pole trailer.

so you need to fix an automatic axle lift device to make it legal for you to tow it.
that being said, you can always get it towed by a wrecker if you want it 100% legal. they have a permit and insurance to tow stuff without all axles being in contact with the ground.
