I doubt the USA/Canada differences are huge, here. NMD90 is evidently rated for exposed use dry or concealed used in dry or damp locations, so no wet locations. Exterior conduit is always a wet location.
The conduit should come through the wall, and you should make the transition from NMD cable to THWN wires in a box inside the building, not outside, or else run conduit the whole way and use THWN wires in conduit the whole way. Which might be easier than you imagine, if you can use corrugated flexible plastic conduit (smurf tube) in Canada, which I expect you can. Flexible metal conduit is also an option. If you have straight runs through the joists, you might not need flex, but many folks prefer flex in that sort of situation. If you have rodent exposure, choose metal.
Regarding ENT and the Canadian electrical code - most recent I could find without paying money was 2012, but here's the code language, and it does not appear to require concrete encasement as claimed in a comment.
Electrical non-metallic tubing
12-1500 Use Subject to the provisions
of Rules 2-128 and 12-1502 to 12-1514, the installation of electrical
non-metallic tubing shall be permitted(a)underground in accordance
with Rule 12-012; and (b)in exposed or concealed locations.
Restriction on use Electrical non-metallic tubing shall not be used
unless provided with mechanical protection where subject to damage
either during or after construction.
12-1504 Supports Electrical
non-metallic tubing shall be securely fastened in place within 1m of
each outlet box, junction box, cabinet, coupling, or fitting, and the
spacing between supports shall be not more than 1m.
number of conductors A tube shall not contain more conductors of a
given size than are specified in Rule 12-1014.
limitations (see Appendix B) (1)Electrical non-metallic tubing shall
not be used where normal conditions are such that any part of the
tubing is subjected to a temperature in excess of 75°C.(2)Subrule (1)
shall not prevent the use of insulated conductors having temperature
ratings in excess of 75°C, but such conductors shall not have
ampacities exceeding those of 90°C conductors regardless of their
12-1510 Connections and couplings (1)Where lengths
of electrical non-metallic tubing are coupled together or connected to
boxes, fittings, or cabinets, fittings designed for the purpose shall
be used.(2)Where lengths of electrical non-metallic tubing are coupled
together underground, the couplings shall be applied using a solvent
cement suitable for the purpose.
12-1512 Support of equipment
Electrical non-metallic tubing shall not be used to support electrical
12-1514 Provision for bonding continuity A separate
bonding conductor shall be installed in electrical non-metallic tubing
in compliance with Rule 10-404.
2-128 Flame spread requirements for totally enclosed non-metallic
raceways (see Appendices B and G) Totally enclosed non-metallic
raceways installed in buildings shall meet the flame spread
requirements of the National Building Code of Canada
Use duct seal (a grey non-hardening putty made for the purpose) to plug the conduit around the wires at the wall penetration, to reduce interior condensation.
The conduit outside will have to be buried at the code-approved depth (which I'm more familiar with the NEC then CEC version of - it varies with conduit type and protective concrete layers, or lack of same, typically), and may have to be schedule 80 in any locations considered exposed, assuming our codes are more similar than different. In many cases just using schedule 80 the whole way makes the most sense.
