We're not New York. It's a silly law and it hampers Saskatoon's growth.

Well, Saskatoon is not New York: the distances are vast in NYC compared to micro-cosmic Saskatoon. (YXE is essentially 'adjacent' to Saskatoon's CBD.)
The approach to Runway 33 is perfectly fine-and-dandy to utilize for a straight-in approach in VFR (Visual Flight Rules) conditions; however, Runway 33's IFR (Instrument Flight Rules) approach is less forgiving. The IFR approach to Runway 33 is a VOR/DME-type approach. VOR/DME-type approaches are not required to precisely line up to the runway centre line: they are instead, assigned the most appropriate VOR radial in order to achieve the greatest degree of success of landing once the runway environment has been sighted upon "breaking out" or achieving visual at minimums. This is based on the virtue of the VOR facility's location on the airfield. The approach to Runway 33 is actually 11 degrees counter-clockwise from the heading of runway 33. (Which happens to skew it directly over the downtown core.)
And now: IFR Minimums:
MDAs. (Minimum Descent Altitudes) The relevant MDA for the aforementioned IFR approach to Runway 33 between SASOD (3.6 NM away) and LIDEX (1.8 NM away) is 594' AGL. (Or Above Ground Altitude.) If you prefer, it's 181.05 metres AGL.
Once past LIDEX, the final MDA is 353' (or 107.6 metres) for the runway.
Downtown Saskatoon lies between 1.8 and 3.6 NM from the runway threshold.
An aircraft, no matter how large or small, while conducting an IFR approach, is permitted to descend down -
but not below - the lowest relevant MDA along the approach published in the CAP (Canada Air Pilot) before achieving visual of the runway environment. If visual is not achieved, then a Missed Approach must be executed.
Based on the premise here, I can't see Saskatoon's height limit being raised anytime soon: If 95 metres is Saskatoon's height limit, 181 metres is already pushing it for IFR inbound traffic. 86 metres isn't a hell of a lot of headroom for a B757's landing gear to clear tall rooftops (at this time) --
especially -- when in IMC. (Instrument Meteorological Conditions.)
Furthermore, if Runway 09/27 were to be unserviceable, for any reason, and the wind is out of the northwest and conditions are IMC, then runway 33 would then be the only gig in town.
I would suspect that would be as to why things are what they are for height restrictions.
I hope this helped you guys in clarifying this height mystery a bit.
