Most hills won't let any uphill travel before the hill opens in the morning if they're doing avalanche control.
At my hill the main lift is just up from the base, so a small crew of us hike up there on the big pow days to avoid the craziness of the base area, and they're cool with that.
I know that Revelstoke had to actively warn people this winter about hiking the mountain at night during full moons. Apparently they weren't really using their heads and skiing in areas where the winch cat was operating... that could have gotten messy.
Other places, like Whistler DO NOT allow any uphill travel in the morning. They only check lift tickets at the base lifts, so a way for poor ski bums to ski without paying is to hike up in the morning to the second set of lifts. If you are caught by staff while doing this they will kick you off. Some might be dicks and try to charge you with trespassing, others will maybe try to guilt you but let you keep on hiking 'cause they're cool like that.
Seeing as you're in Alberta and you are talking about terrain that likely sees avalanche control work, it is highly probable that the resort will not be okay with uphill travel outside of operating hours, and possibly still not be cool with it during operating hours.
The fact that it is on park land makes no difference. The resort has a lease in place to allow them to operate and if your presence is hindering their operations in any way, they have the right to tell you to get lost.
That said, there are resorts that allow and even promote uphill travel, so check with the resort in mind. If they say no, respect their decision. Not knowing something is not allowed does not make it excusable.
At my home hill, they technically cannot prevent uphill travel because the ski hill is in a public park. You can hike all day if you don't want to buy a pass. But that's a rare situation, and this is Minnesota, anywhere where there is risk of an avalanche, or you are skiing on private property, you pretty much can't do that.

this type of situation is exactly why brighton got sued and put the PEEPS program in place... do whatever you want, but don't be dumb, don't get hurt, and if you do get hurt, don't be a dick and sue your local mountain
You can probably hike like the half pipe a little bit before they open or a rail near the bottom. I have hiked sunday river at night when i should just buy a night pass but instead hiked up and skied under the lights.

Now being a park crew member at a certain 400 foot hill in Edmonton, I can tell you one thing. Don't do it. If you hike before there are any signs up there could be huge liability issues, even then, if you get hurt it's a huge waste of resources and patrol may not even come (depending on when you're there).
The truth behind this is not black & white, but more so shades of grey.
The lease allowing for operation on public forest land gives the ski area/resort operator the power to restrict access during times when ski area/resort operations are on-going. Operations can be defined as anything from avy control to grooming operations to other ops work that could be taking place such as an employee snowmobiling from point A to point B. It becomes even greyer when you begin talking about skinning/hiking on trails that have been maintained - trail cutting, snowmaking, grooming, etc. Additionally, the lease agreement gives the ski area/resort operator the power to close access for operational reasons as they see fit.
While many places have no problems allowing respectful and mindful users to travel uphill, they do not have to just because it is National, State or Provincial land. Their lease gives them the right to tell you to get lost if they deem that your presence hinders their operations.
