Probably Norway maple, if not, sugar maple. Best way to tell them apart: look at the terminal bud on the twigs in fall--if its fat, its Norway, if its long and skinny, its sugar. Other ways to tell them apart are not so foolproof due to differences between individual trees, though generally Norway Maples stay green longer, leaves turn yellow or brownish (sugar maples often have red/orange or red and yellow leaves--can be very colorful), and have less deeply cut leaves than sugar maples.
Couple other ways to tell sugar and norway maple apart:
1) Norway maple leaves are usually wider than they are long, sugar maples are about even.
2) Norway maples have white sap. When the leaves are green, if you pull one off and look at the base of it where it broke, you can see the milky sap leaking out. Sugar maples have clear sap.
